      We had an MDS crash with the following assertion:

      ldlm_lock.c:770:ldlm_lock_addref()) ASSERTION( lock != ((void *)0) )

      The previous few minutes contained many lock timeouts and some node reconnections.

      The backtrace for the mdt_02_049 that hit the assertion was:

      ldlm_lock_addref
mdt_reint_open
mdt_reconstruct_open
mdt_reconstruct
mdt_reint_internal
mdt_intent_reint
mdt_intent_policy
ldlm_lock_enqueue
ldlm_handle_enqueue0
mdt_enqueue
mdt_handle_common
mds_regular_handle
ptlrpc_server_handle_request
ptlrpc_main

      We were running lustre version 2.4.2-14chaos (see github.com/chaos/lustre).

      We cannot provide logs or crash dumps from this system.
