SNMP polling problem

We upgraded from v7.8.5 to v8.1 (HF4) two weeks ago. We started with one, then it progressed to 3 and now expanded to 4 today, Win2K servers that have spiked to and hold at 100% CPU, no memory graphed and all interfaces and volume state changes to "unknown". We also have discovered some (haven't worked the number yet) Cisco routers showing no CPU & memory (No Data for Selected Period) and all interfaces "unknown". When we try to rediscover the servers using SM (ListResources), we get "Interfaces-MIB not supported". When we try to rediscover the routers using SM (ListResources), we get "Routerx is currently down, unreachable, or xxxx is not a valid community string". We have double and triple-checked the SNMP configs are correct. We tried to Unmanage/Manage but no change. With that said, we took a sniffer capture of the problem. In our initial analysis looking at a good polling period before the change, we see the good SNMP Gets/Replys to the Host-Resources-MIB then, for some reason, the device starts responding to Gets with Reply SNMP General Error (5). Soon thereafter, Orion switches to Gets to the Enterprises-UCDavis-MIB (2021). So, our thought is, it's the SNMP Agent on the server so we stopped and restarted the SNMP service...no change. Due to the high visibility of the server we have not been able to reboot it to see if it clears the problem. We'll be opening a ticket soon and move on to looking at the router exchange.

Is anyone else experiencing this behavior?

We can't see your text.

Yes. This software has a bug. Apparently with IE6 and no SP2 installed there are issues. Use FireFox until we can get this patched.

I wonder if your problems could be at all related to this thread.

I know its not the exact same problem, but the "wacky poller syndrome" after installing 8.1 HF4 doesn't seem so uncommon.

Just a thought.

We are running 8.5.1 and are experiencing the same problems.

Butch-

Could you elaborate on the issue you have now so someone might be able to offer current suggestions? This thread dates back to last summer and some of these issues may have been addressed since then.

I have seen this also seems to not be consistent. Saw it in v7.8.

reboots will sometimes fix it for a while and other times not make a difference and it will come back still showing unknown state.

I am also seeing this problem and it's random. I have a Windows 2000 Server that Orion can't report on and a Sidewinder that suddenly stopped reporting statistics. No changes have been made to it. We have confirmed the community string and as someone posted early the system has high visibility and can not be rebooted without change control.
