Solarwinds SNMP

[mmcgurty]

Having recently purchased Solarwinds Engineer's Edition I was really stoked to be making some really useful graphs of bandwidth and utilization. I ran the following Solarwinds applications on a seperate PC collecting stats all day long. Network Perfomance Monitor, Advanced Bandwidth Monitor, and the Router CPU Load utilities. All routers and switches being monitored have SNMP enabled to support the full functionality of Solarwinds SNMP "gets" for graphing/stats purposes.

However, about two weeks after running it I started experiencing routers crashing due to the following:

System restarted by error - a SegV exception, PC 0x80362664

I contacted Cisco about this problem and they said it was the following:

"The crash had snmp processes in it. Looks like it was trying to get interface stats when the crash occured."

We determined it was Solarwinds, since its the only SNMP software we run to check the routers/switches.

My question, am I doing something wrong on my router configurations for this to be happening, anyone else experiencing these problems, should I quit using Solarwinds?

You're probably overwhelming the router with all your requests.

Solarwinds gets its data from seperate SNMP GET requests where other applications (HPOV) use MGET (multi-GET) which is a lot less intensive on the router.

I used the advanced port bandwidth program and ended up flooding a 7204 with UDP SNMP requests.

SNMP is great, just recognize its weaknesses and (huge) vulnerabilities. Never enable a RW community string!
