Description Luke Schierer 2007-06-25 17:37:52 UTC
Description of problem:
After enabling cachefilesd, the server kernel panics after only a few files are
read via nfs.  

Version-Release number of selected component (if applicable):

How reproducible:
Every time. 

Steps to Reproduce:
1. configure cachefilesd to cache to /var/fscache on an install with standard RH
2. start cachefilesd
3. start to pull files over nfs for serving with httpd.
Actual results:
The entire system crashes, we do not see any record left in the logs of why. 
This does not happen when cachefilesd is not enabled. 

Expected results:
The system should at worst not kernel panic.

Comment 1 Luke Schierer 2007-06-25 18:14:48 UTC
on further investigation, this appears to happen only if the cache is
invalidated by an updated (or newly created) file. 

Comment 2 Steve Dickson 2007-06-27 03:39:14 UTC
Would it be possible to get an oops back trace?

Comment 3 Tom Coughlan 2008-03-13 13:20:47 UTC
This has been NEEDINFO for 8 months. It may be a duplicate of 

BZ#279431 - kernel panic when using rhel5.1 and fscache

but we need a stack trace to know, or to otherwise make any progress on this. 

Will you be able to test this again?
