CIFS in RHEL4 U3 was updated to the 1.34a release. Please try
that kernel to see if the this problem is resolved.

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 02:19:59 EST
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 18:32:36 EST
Everything is fine with 24.EL, bug seems to be related with unmountable CIFS server.
