      One of our MDS nodes crashed to day with the following assertion:

      client.c:304:ptlrpc_at_adj_net_latency()) Reported service time 548 > total measured time 165
osp_sync.c:355:osp_sync_interpret())  ASSERTION( rc || req->rq_transno ) failed

      Note that the two messages above were printed in the same second (as reported by syslog) and by the same kernel thread. I don't know if the ptlrpc_at_adj_net_latency() message is actually related to the assertion or not, but the proximity makes it worth noting.

      There were a few OST to which the MDS lost and reestablished a connection a couple of minutes earlier in the log.

      The backtrace was:

      panic
lbug_with_loc
osp_sync_interpret
ptlrpc_check_set
ptlrpcd_check
ptlrpcd
kernel_thread

      It was running lustre version 2.4.2-14chaos (see github.com/chaos/lustre).

      We cannot provide logs or crash dumps for this machine.
