Thank you for the reply. I ended up re-installing the plugins. It seemed to fix the problem. I just found it rather strange that all of sudden the plugin stopped responding.
...and, changing the community string as well.

Also, just a security-minded suggestion, you should probably change the community strings. SNMP - "Security? Not My Problem." :) Cheers This message and any attachments are intended only for the use of the addressee and may contain information that is privileged and confidential.
