> Key: VFS-120
> URL: https://issues.apache.org/jira/browse/VFS-120
> Project: Commons VFS
> Issue Type: Bug
> Affects Versions: 1.0
> Environment: Tomcat 5.5
> JDK 6.0 (build with JDK 5)
> commons-vfs-1.0.jar:
> Specification-Title: Commons VFS
> Implementation-Version: 1.0
> JSCH: jsch-0.1.31.jar
> Reporter: Harald Brabenetz
> Priority: Critical
> Attachments: SftpFileSystem-patch.txt
>
>
> The error occured after restarting if the SFTP-Server was KILLed!!.
> With a normal shutdown of the SFTP-Server, no exception after restarting
> occured.
> I found no function to force the reset of the session in SftpFileSystem.java
> There is a function:
> DefaultFileSystemManager manager =
> (DefaultFileSystemManager)VFS.getManager();
> manager.freeUnusedResources();
> But this works only if AbstractFileSystem.isReleaseable() returns true.
> And this this function return only true if all SFTP-FileObject are removed
> from the GarbageCollection (finally()-Methode).
> I cannot force a GarbageCollection.
> So there is no way to handle this Error! I must restart the VM
> (ServletContainer).
