Re: [SourceJammer-devel] File Locking issue, possibly session timeout ?

[Anin <ani...@pa...>]

Rob,
 
  I am running sourcejammer server 2.1.0 on Tomcat 5.5 with JDK 5. I am 
connecting using the 2.1.2 beta client. I see this error once in a while 
on the server logs. It makes some directories completely unbrowsable in 
the archive. The only way to fix it is to perform a restart and it goes 
away.. I am thinking maybe it is something to do with the beta client 
that I am using, session management problems etc. But please tell me if 
something jumps out from this stack trace.

Thanks,
Anin
