Description

when we simulate message drop for portal 17 (LDLM_CANCEL_REQUEST_PORTAL) and portal 18 (LDLM_CANCEL_REPLY_PORTAL), I saw this failure on client and application failed.

LustreError: 13507:0:(layout.c:2042:__req_capsule_get()) @@@ Wrong buffer for field `dlm_rep' (1 of 1) in format `LDLM_INTENT_GETATTR': 0 vs. 112 (server)

Application is quite simple, just a MPI program which repeats to fstat and fchmod on two nodes.
