[jcifs] Transport1 timedout waiting for response to SmbComSessionSetupAndX

[Vladimir Volodin]

Hi All,

We're developing an integrated solution using glassfish esb, alfresco and liferay, and we're using samba for file exchange between those components.
Right now we're constantly running into jcifs errors (listed below) mostly on exists() calls. Network connectivity is ok, everything's on LAN, no packet drops or anything.
Any ideas why this keeps happening?
