Description

(moved here from site triage:)

I experienced following panic on two OI-boxes simultaneously, however these two servers do not share any i/o systems but they do share identical workload, therefore I'm suspecting software issue.

"panic message: stmf_svc: I/O deadman hit on STMF_CMD_LU_OFFLINE after 1000 seconds"

stmfadm was called before problem was exposed. No offline/remove-related procedures though, just adding few luns and views.
Servers are Dell R720 and crashdump is found at http://www.mui.fi/vmdump.0
Other system that had same issues (different datacenter, similar setup) http://www.mui.fi/vmdump.1
As workaround I disabled stmf deadman by: echo stmf_io_deadman_enabled/W0 | mdb -kw

I suspect this could be related in https://illumos.org/issues/3621 ?

Thanks for your thoughts!
