We are seeing openAFS client kernel crashes on a server that is using
both AFS and lustre clients. This happened using openafs 1.6.5 and
1.6.6. These machines are running a lustre client version 2.1.5. The
OS on the server is RHEL 6.5. We currently are not sure what is causing
these crashes. (we have not moved to the 2.6.32-431.5.1 kernel since it
is not offically supported by lustre).
Any help with this issue would be greatly appreciated. Please let me
know if you need any additional information.
Thanks for all of your help on this.
