Updated by Zheng Yan over 8 years ago

Subject changed from LibCephFS.ThreesomeInterProcessLocking failed with lockdep to LibCephFS.LibCephFS.InterProcessLocking segment fault.
Status changed from New to Need More Info

The lockdep errors are side effect of previous failiure.

LibCephFS.InterProcessLocking failure is caused by child process segment fault. But there is no clue in the ceph-client.log (segment fault happened after umount)
