Hello we are experiencing a strange behaviour of VFS with vsFTPd with 2.1-SNAPSHOT version on trunk. We have a cycle in which periodically tests if a file exists, exiting once it has been found. If the vsFTPd session timeout (idle_session_timeout parameter) has been met, we receive a FileSystemException, due to a broken pipe (see stack trace below). It seems that the problem happens when sending the QUIT command after a failed LIST.
I would like to fix this problem with a patch, however: 1. do you think it is a bug at all? 2. what is the best strategy? Trapping the exception in FtpClientWrapper.disconnect? Or in .listFiles? Thanks in advance Antonio ------------ The stacktrace and relevant log: --> Log before exception PORT 127,0,0,1,220,47 421 Timeout. --> Stacktrace org.apache.commons.vfs2.FileSystemException: Could not determine the type of file "ftp://localhost/xxx";. at org.apache.commons.vfs2.provider.AbstractFileObject.getType(AbstractFileObject.java:1526) at org.apache.commons.vfs2.provider.AbstractFileObject.exists(AbstractFileObject.java:1022) at mystuff...
