I've been working on trying to resolve a mutex timeout with a MSA 2040 SAN we've been monitoring. We had been successfully monitoring the SAN with the SSH sensors, but recently the sensors began to fail with mutex timeouts. I've tried lengthening the scanning intervals (from 60 seconds to 5 minutes), but without success. There are three sensors are the enclosure and two logical disk sensors. They are currently paused. I've also tried adding a new enclosure and a new logical disk sensor with the default configuration settings, and both fail with the same error.
I do have another MSA 2040 that did not have any sensors (other than ping) configured at the same location, so I decided to try and add an enclosure sensor on it. It worked successfully. So it seems like something with the MSA 2040 I'm having this issue on is the culprit. I think a reboot might resolve the issue, but I'm looking to see if there is another suggestion without rebooting the SAN?
