Been fighting this for weeks now... MSM 760 controller that continually seems to restart on its own. Have a case open with HP on it, escalated to level 2, still no resolution. Unsure when the problem actually started occuring, but we know it's been happening since at least early-mid Janurary. That was when we setup a syslog server and began noticing this. It very well MAY have been happening before mid January, we just don't have any syslogs prior, or proof of the reboots. The MSM controller has about 25-30 422 APs, and 1 430 AP. The reboots happen quickly enough that it doesn't usually result in helpdesk tickets or user complaint.
In late December the MSM controller was upgraded from 5.5.3 to 5.7.0.0
In early January we added a single MSM 430 AP to the environment.
In early Feburary we upgraded the controller from 5.7.0.0 to 5.7.0.2
There is nothing in the syslogs showing anything as to a reason for the reboots.
We have replaced the MSM controller itself (warranty replacement), the 2 patch cables, and the 1 power cable. We have made sure the unit is plugged into a UPS unit that is not being reported as going from AC to DC power. We have done a complete factory reset of the controller and re-loaded the configuration by hand. We have unplugged the single MSM430 that we added in early January. We have even moved the iPort and LAN port from a 5406 chassis to a E2520 chassis. So far, we still continue to get reboots as much as 4-5 times a day on the controller.
I am likely now going to back-rev the controller to 5.5.3 and manually re-do the configuration all over again as the next test.... if that doesn't fix it, we may start turning off APs in bunches, to see if a single AP is causing a controller reset?
Totally stumped here.
Syslogs from the controller (even the debug logs) and the HP switches show NOTHING prior to the restart that clues us in to the problem.
HP is wondering if something on the network itself is causing the MSM to restart, but what that could be, who knows, and who knows why?
Any wild ideas here?
