The workloads are very diverse, ranging from mpi to simple single threaded apps.</p> <p>Hi Alex,</p> <p>We are seeing this as well. I haven't yet identified the sequence of events. We see it with a set of test scripts that race to mkdir/rmdir/create/unlink/read/write within a common directory, in a randomized manner. I'll try narrow the set of operations down.</p> <p>Am I correct that the object existed at the very beginning of mdt_getattr (I see assert), but then after mdt_getattr-&gt;mdt_getattr_internal-&gt;mdt_attr_get_complex does not?</p> <p>Is this supposed to be protected entirely by an LDLM lock held by the client?</p> <p>thanks,<br/> Olaf</p> <p>Still seeing this in testing. We need to get this message resolved. Having a flood of messages on the console that sysadmins need to ignore leads to sysadmins that stop looking at the logs and we miss important things.</p> <p>This is a normal situation if there are multiple threads racing to unlink a single file.
