Hi,

In production environment, the Weblogic nodes are failing down sometimes. But this is not happening frequently. I got this common exception whenever the Node fails. jcifs.http.NtlmHttpFilter.doFilter(NtlmHttpFilter.java:171)

I’m looking for your help. Please share your views.

Welcome to JR rajkumar.

I assume you have some sort of documentum related class deployed on that server ? The thread that is handling the HTTP call is taking more than 10 minutes to return. Possible reasons are

1. Thread deadlock
2. Blocking calls
3. Infinite loops
etc

Can you post a thread dump ? WL 10 allows you to take a thread dump at any time when the server is running. Take the dump when you have some stuck threads
 
See ya later boys, I think I'm in love. Oh wait, she's just a tiny ad:
