I'm running openafs 1.4.14.1 on a RHEL6 system and under heavy load when
accessing files in AFS via apache I'm able to consistently trigger a kernel
panic. Below is the output from the "crash" command and includes a stack
back-trace.
Please let me know if/what I can do to help further troubleshoot this.
Thanks!
