[linux-cifs-client] Re: CIFS-VFS error

[Anirudh Srinivasan]

Hi
My kernel version here is :

Linux version 2.6.18-8.el5 (brewbuilder at ls20-bc2-14.build.redhat.com) (gcc
version 4.1.1 20070105 (Red Hat 4.1.1-52)) #1 SMP Fri Jan 26 14:15:21 EST
2007

Red Hat Enterprise Linux Server release 5.2 (Tikanga)

How can i avoid these error from the logs.? Also i see the CPU load spikes
up at around the same time , and this being a web server i think this is
more of a serious issue .

Thank you
