    Description

      While trying to test for LU-7404 OST timeout the one of the OSS nodes became unaccessible via ssh and conman.

      This was running with 2 OSS nodes running 1 zfs zpool on each, 1 mds, and 4 clients running IOR. The first message that was seen was fairly soon after starting. About 2 hours after running lustre stopped responding to lustre clients and static scripts running on the OSS stopped running.

      First message seen was:
      Apr 4 21:06:29 wolf-4 kernel: LNet: Service thread pid 12256 was inactive for 200.30s. The thread might be hung, or it might only be slow an
      d will resume later. Dumping the stack trace for debugging purposes:
