FTOS (DNOS) 9.5 is the version that has the memory leak that will hang a S4810 after a few weeks of Observium polling.

We ran into SNMP memory leaks on our Force10 S4810 switches, which eventually hung the devices and required a hard power reset. (Yuck!)
Dell has published new software that might fix this (Note: I have not tested this yet, and there are still some open SNMP bugs):

Resolved Caveats:

PR# 140566 Severity: Sev 2 Synopsis: The system does not return valid data when SNMP Get operations are performed to retrieve CPU and memory utilization statistics

Hi All,
Couple of our Force 10 (S4810) Switches are reporting high CPU usage which seems to be caused by snmp processes. This is impacting the network performance.
Do we know the MIBS (modules) that cause high load? And how can we disable these MIBs.
Thanks!
