switch randomly rebooting

[paul.delaney]

we are having a memory leakage problem. It takes about 9 months and results in the switch staying running but becoming uncontactable, then after a week or so the switch will randomly reboot. It is happening with DC and IDC models (WS-26-500)

What firmware are you running on them? Various memory leak issues have been solved in recent versions.

[paul.delaney]

we are running 1.5.14 on all switches

1.5.16 has additional memory leak fixes. viewtopic.php?f=17&t=240

Unfortunately there is still a memory leak issue with 1.5.16 we believe to be related to discovery (RTGLW is still investigating) , the more devices on the same management IP space will increase this, disabling discovery and rebooting the host in most cases will stop it from happening. you can just toggle discovery when you need to use it, but running 1.5.16 is your best bet until newer stable releases release.

One of our units must have heard us talking. Looks like we had a switch reboot and most likely was because of a memory event. Looked at our other units and they all seemed to have higher memory usage then I was expecting.

I added a network monitor to track memory usage via SNMP to catch them before rebooting.
