[jcifs] SMB Transport Errors - java.lang.Throwable: at jcifs.smb.SmbTransport.send(SmbTransport.java:608)

[Ghouse, Sherjeel]

We are using jCIFS 1.2.12 to enable NTLM SSO for one of our Web Apps. We ran into the following exception resulting in single point application failure. If I remember correctly, a fix was put in place to prevent SMB Transport errors. Does anybody has any idea why jCIFS is not handling SMB Transport Errors. The Transports didn't Timeout and the users waited indefinitely for a reponse from the Application Server.

Servlet failed with IOException
