Hi All,
Thanks for you reply!
We have 9 Force 10 S4810 switches. Out of which three are running 8.3.12.0 and others are running 9.4(0.0P1).
We seeing this issue with two of the switches running 8.3.12.0. However, one of the Force 10 running 8.3.12.0 doesn't have the issue.
I believe, I have started seeing this issue couple of days back.
The issue seems intermittent. Please see the attachments.
I ran a continuous ping to the switches but never is any disconnection there. The CPU processes on the switches doesn't show high CPU. So, not sure what causing the issue.
Regards Renuka

Which software versions were you running when you saw these bugs?

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# 139394 Severity: Sev 2 Synopsis: System in stacking configuration may reboot when SNMP operations are executed to retrieve CPU/Memory utilization statistics
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

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!
