      Description

      Hi,
      We have a type of job that keeps crashing Lustre client version 2.10.5 with the following trace. It is very likely this job has files open on Oak (Lustre 2.10.4). This looks like old tickets LU-1414 and LU-118... fixed in Lustre 1.8! The issue happens on a bigmem node (1.5TB of RAM), and doesn't seem to happen on node with less memory. I'll try to upload a crash dump file to your ftp.
