Description

Under performance testing with the SCST iSCSI driver on top of RBD (we'll switch to LIO at some point in the future, but probably a fair bit later), this crash occurs after a few hours of perf benchmarking.
I'm investigating whether we can run those same block io tests directly on top of RBD, but they may have Windows initiators (checking into that).

I'm attaching the kernel log.. and unfortunately I turned off ceph logging (ms=0) for this run to make sure logging isn't affecting performance.

I can probably recreate with ms=1 if it'll help.

I've included a bunch of the kernel messages in the runup to the crash (rsyslogd over udp), though most of it's scst stuff.
