We will need a fix for b2_5 (we are going to transition to b2_5 in a few weeks).</p> <p>We have additionally seen the error message with the LDLM_ENQUEUE_LVB name instead of LDLM_INTENT_GETATTR. Am I correct in assuming that is the same problem?</p> <p>Chris, if the request corresponding to the LDLM_ENQUEUE_LVB name had a 192-byte reply length (please look for "lens ???/192"), I would assume that was due to the same problem (i.e., a ping being mistook as a normal reply). I'll get the patch going as soon as my vacation is over.</p> <p>Oops, s/a ping/an early reply/.</p> <p>The patch has been updated with problem description.</p> <p>Yes, for LDLM_ENQUEUE_LVB it is 328/192.
