    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). org.apache.commons.vfs.FileSystemException: Could not copy "file:///C:/TEMP/....." to "sftp://......". at org.apache.commons.vfs.provider.AbstractFileObject.copyFrom(AbstractFileObject.java:902) at com.bearingpoint.orf.chat.core.service.ExportManagerImpl.exportChatMessages(Unknown Source) at com.bearingpoint.orf.chat.core.service.ExportManagerImpl.startExportNow(Unknown Source) at com.bearingpoint.orf.chat.core.service.ExportManagerImpl$ExportManagerRunnable.run(Unknown Source) at java.lang.Thread.run(Thread.java:595) Caused by: org.apache.commons.vfs.FileSystemException: Could not write to "sftp://chat:chat@10.1.5.130/home/chat/chatfile_12.zip". at org.apache.commons.vfs.provider.AbstractFileObject.getOutputStream(AbstractFileObject.java:1227) at org.apache.commons.vfs.provider.DefaultFileContent.getOutputStream(DefaultFileContent.java:373) at org.apache.commons.vfs.provider.DefaultFileContent.getOutputStream(DefaultFileContent.java:356) at org.apache.commons.vfs.FileUtil.copyContent(FileUtil.java:100) at org.apache.commons.vfs.provider.AbstractFileObject.copyFrom(AbstractFileObject.java:893) ... 4 more Caused by: org.apache.commons.vfs.FileSystemException: Could not connect to SFTP server at "sftp://chat:chat@10.1.5.130/". at org.apache.commons.vfs.provider.sftp.SftpFileSystem.getChannel(SftpFileSystem.java:144) at org.apache.commons.vfs.provider.sftp.SftpFileObject.doGetOutputStream(SftpFileObject.java:402) at org.apache.commons.vfs.provider.AbstractFileObject.getOutputStream(AbstractFileObject.java:1219) ... 8 more Caused by: com.jcraft.jsch.JSchException: session is down at com.jcraft.jsch.Session.openChannel(Session.java:756) at org.apache.commons.vfs.provider.sftp.SftpFileSystem.getChannel(SftpFileSystem.java:122) ... 10 more
