Comment 2 Steve Dickson 2005-12-05 20:07:20 UTC 
CIFS in RHEL4 U3 was updated to the 1.34a release. Please try
that kernel to see if the this problem is resolved.
Comment 3 Erki Simson 2005-12-06 08:45:05 UTC 
I'll give it(24.EL) a try. Don't expect any results soon as
our problem showed up only after half an year of CIFS use.
Comment 4 Erki Simson 2005-12-13 07:19:59 UTC 
So far everything seems OK with 24.EL
I noticed that 24.1.EL has CIFS related patch(#170498), should
i upgrade to 24.1.EL ?
Comment 5 Erki Simson 2006-01-06 23:32:36 UTC 
Everything is fine with 24.EL, bug seems to be related with unmountable CIFS server.
CLOSE ?
