Summary: Windows XP Guest crashes when doing recursive grep in
a Clearcase environment
Product: Virtualization
Version: unspecified
Kernel Version: 2.6.32-22
Platform: All
OS/Version: Linux

I have the following problem reproduced on centos6 and RH6.
When I am doing a recursive grep on my Clearcase view using a 3rd party program
called Windows Grep. On every run, the VM would crash (windows kernel crash
where the cause is reported as unknown by Microsoft) up after the program ran
about an hour or so.
