# Description of problem:
System crashed. I have only a screenshot (attached).
The system has two nfs resources mounted. cachefilesd is used to optimize.
The data in that mounted dirs is used by the webserver (htdocs).
# Version-Release number of selected component (if applicable):
$ rpm -qa | grep cachef
$ uname -a
Linux srv-sl0a.ccds.de 2.6.32-358.18.1.el6.x86_64 #1 SMP Wed Aug 28 17:19:38 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
rpm -qa | grep nfs
# How reproducible:
I can not reproduce it - it just happens today the first time.
The cachefilesd is setup since 5 days. I hope the screenshot helps.
# Actual results:
# Expected results:
# Additional info:
du -h -s /var/cache/fscache/
# nfs mount options

kernel panic screen shot
Fix is included in RHEL 6.5
Please check whether you notice this problem with RHEL 6.5
With reference to your email in linux-cachefs list.. Can you confirm whether you notice the panic when you use the standard RH kernel ?
So far no problems with EL6.5. Thank you for your input!
