Java io ioexception there are no more files

Exhausted Files: Java.io.IOException

Upon transferring the file server to a different host and ensuring that the permissions and path references were verified multiple times, we encountered a java.io.ioexception while copying the files to their new location within the code. Inquiries have been made about a setup in Azure DevOps pipeline that is responsible for backing up both rdb and analysis databases from a database-hosting server to a separate server that has a shared location.

Java.io.IOException: There are no more files

The code I received includes a function for transferring a .pdf file from one location to another. During this process, new folders are created and named using hash values. The function also stores the new path in a database, which is later utilized by a BI tool to access the file through an API.

Once the file server was relocated to a new host and we confirmed the permissions and path references multiple times, an error message with code java.io.ioexception appeared during the file transfer to the updated location within the code. As a result, the copy process failed, folders were not generated as needed, and the API could not access the files.

According to the log files, the program efficiently recognizes the source file and constructs the destination path with accuracy.

Do you have any insights on the root cause of the IOexception? It’s a new issue for me, and I’ve been unable to locate a similar discussion online.

By searching for «There are no more files» on Google, you can find individuals facing challenges with security software, particularly ASUS Data Security Manager. As a result, I doubt that the issue lies within your Java code. To confirm this, you may try copying a file manually, such as the following example:

copy some.file "\\tf-fs-1\arcstor\fc\fc3533e07547850176b671730ddccfcc" 

Based on your error message, I was able to determine the path, but please verify its accuracy. It is possible that enclosing the path in quotes may be necessary. However, there is a chance that the path may be obstructed by an element on the remote machine, resulting in the failure of the process.

I encountered a comparable issue where FileUtils.copyFile(file, newFile) was utilized in a loop. However, after 258 copies, I would receive the error. To resolve this, I modified my code to use Files.copy(sourcePath, destPath) instead, and the issue was resolved.

Analysis service database backup error

My pipeline, azure devops, is designed to back up both rdb and analysis db from the database server to another server with a shared location. While the relational databases are always successfully backed up, the analysis db backup fails every time, with a different database causing the same error. The complete error stack can be found below, along with **There are no more files** .

Could the reason for the backup failure be due to attempting to back up to a shared location via network? The backup process runs for approximately 10 minutes and only manages to back up a few databases before failing. Interestingly, I was able to successfully backup databases from a different server to the same location without any problems, and it only took a couple of minutes to complete.

As the failure persists across various analysis databases, it is proving to be difficult to identify the root cause. Any assistance in resolving this issue would be highly appreciated.

A corrupted database led to the backup failure. However, the issue was resolved by dropping the database and restoring it from a previous copy. Since then, the pipelines have been running smoothly for a few days.

Does Java need to support ERROR_NO_MORE_FILES when canonicalizing paths on Windows?

The problem.

A Java-based daemon operating on Windows 7 is responsible for transferring files from one directory to another. The source and target directories are both hosted by Windows Server 2016 and are designated as network share. The copying process utilizes Apache Commons IO and may encounter errors resulting in a stack trace and an error message that indicates a lack of files.

java.io.IOException: Es sind keine weiteren Dateien vorhanden at java.io.WinNTFileSystem.canonicalize0(Native Method) at java.io.WinNTFileSystem.canonicalize(Unknown Source) at java.io.File.getCanonicalPath(Unknown Source) at org.apache.commons.io.FileUtils.copyFile(FileUtils.java:642) at org.apache.commons.io.FileUtils.copyFileToDirectory(FileUtils.java:587) at org.apache.commons.io.FileUtils.copyFileToDirectory(FileUtils.java:558) at de.am_soft.osgi.dokliste.eingaenge.impl.internal.Eingang.copyFilesToDbxmlFolders(Eingang.java:283) 

At line 642, only the code if is present in Apache Commons IO, and not the exception.

if (srcFile.getCanonicalPath().equals(destFile.getCanonicalPath()))

The issue does not lie in the act of copying, but rather in the creation of canonical paths. This has been confirmed through the use of Process Monitor1 on the client side where the daemon is operating. The final event prior to the daemon registering the aforementioned exception involves an attempt to send error emails using Logback and other actions. The event’s outcome ( NO MORE FILES ) is a precise match to the error message found in the stacktrace.

10:12:06,6244515 integration.exe 6928 QueryDirectory \\HOST\SHARE$\DocBeam3\[. ].zip NO MORE FILES Filter: 20191106-081920-[. ].zip 

Moreover, based on the previous ProcMon logs, it is evident that the exception occurs exclusively for destFile . When running the daemon on my personal computer, the same event ( NO SUCH FILE ) is consistently recorded.

19:08:03,7485947 java.exe 6232 QueryDirectory C:\Users\[. ].zip NO SUCH FILE Filter: 20191022-143101-[. ].zip 

After debugging the native methods, I discovered lastErrorReportable that specifically verifies certain special error codes but omits ERROR_NO_MORE_FILES from the initial event. However, it includes ERROR_FILE_NOT_FOUND from the second event.

 if ((errval == ERROR_FILE_NOT_FOUND) || (errval == ERROR_DIRECTORY) || (errval == ERROR_PATH_NOT_FOUND) || (errval == ERROR_BAD_NETPATH) || (errval == ERROR_BAD_NET_NAME) || (errval == ERROR_ACCESS_DENIED) || (errval == ERROR_NETWORK_UNREACHABLE) || (errval == ERROR_NETWORK_ACCESS_DENIED))

The link to the canonicalize_md.c file in the libjava directory on the openjdk GitHub repository can be found on line 131.

Whenever the error code ERROR_NO_MORE_FILES arises, the process of path canonicalization is not ignored like in other errors; instead, it terminates with an error.

if (!lastErrorReportable()) < if (!(dst = wcp(dst, dend, L'\0', src, src + wcslen(src))))< goto err; >break; > else

This link leads to line 246 of the canonicalize_md.c file found in the libjava directory of the openjdk/jdk repository on GitHub.

The exception that was thrown is appropriate for my situation, and the message provided is simply a backup that was not necessary in my case.

if (rv == NULL && !(*env)->ExceptionCheck(env))

The link to the code in the WinNTFileSystem_md.c file on the openjdk/jdk GitHub repository can be found at line 258.

Additional observations.

Currently, the daemon doesn’t always fail during file copying, but rather infrequently. However, when it does fail, it appears to be due to the presence of other directories and files in the target directory. Although these directories and files are unrelated to the daemon and are not iterated by ProcMon, their mere existence seems to make a difference. Interestingly, in my local setup, having files and directories in the target directory doesn’t seem to affect copying, and ProcMon never logs event ERROR_NO_MORE_FILES . Nonetheless, after clearing the directory where the problem occurs, ProcMon logs event ERROR_FILE_NOT_FOUND once again.

The question.

Apparently, Windows uses ERROR_NO_MORE_FILES as the final error code when invoking FindFirstFileW , which is utilized by wcanonicalize under specific, unidentified conditions. Unfortunately, as exception list in Java does not contain this code, copying fails in these situations, despite the fact that it appears to be a completely legitimate scenario. Other than that, I do not observe any actual errors.

Is it necessary to include ERROR_NO_MORE_FILES into lastErrorReportable ? And if it is, who should I seek for clarification? 🙂

The reason behind this behavior is an SMB incompatibility between Windows Server 2019 (file server) and older versions of Windows (clients). The difference in handling the cache of directory metadata is responsible for the problem while accessing a share with a large number of files and folders.

Regrettably, a solution for this bug has not been made available by Microsoft yet.

To address the issue, a possible solution is to modify the registry settings on the client side and turn off the caching of SMB metadata. The following code can be used: \ \ \ \ \ HKLM\System\CurrentControlSet\Services\LanmanWorkstation\Parameters\DirectoryCacheLifetime=0\ \(DWORD\)\ \ \ \ .
