Hi
We use jcifs 1.2.9 on a portal server where many simultaneous
connections for different users have to be managed simultaneously in the
same Tomcat context.
Some times, a deadlock appear and leave most of our threads in the
"BLOCKED" state.
With jstack, we discover that all of the theses threads are blocked at
the same line :
Thread 26101: (state = BLOCKED)
-
jcifs.smb.SmbTransport.getSmbSession(jcifs.smb.NtlmPasswordAuthentication)
@bci=0, line=122 (Compiled frame)
- jcifs.smb.SmbFile.connect() @bci=35, line=787 (Interpreted frame)
- jcifs.smb.SmbFile.connect0() @bci=1, line=761 (Compiled frame)
- jcifs.smb.SmbFile.listFiles(java.lang.String, int,
jcifs.smb.SmbFilenameFilter, jcifs.smb.SmbFileFilter) @bci=93, line=1587
(Interpreted frame)
- jcifs.smb.SmbFile.listFiles() @bci=7, line=1495 (Interpreted frame)
- Portlet code...
Did somebody already see this problem ?
