Squid is running on the same machine but implements its own agent,

walk my MIB with the proxy for Squid enabled, the walk terminates
badly.
This seems to be a continuation of a thread you started about a month
ago:
http://sourceforge.net/mailarchive/forum.php?thread_id=7155293&forum_id=4959
Is this just a summary of the discussion back then (which you should
have referenced) or does it contain any new information?

If these conditions are related, I'm unaware of it, though they both involve
proxying for Squid. My previous post was about the SNMP agent crashing
(segfaulting, I believe) when proxying for Squid. Though I'm not aware of
a fix for that issue, I got a fix from the Squid team that to avoid the
issue.
(Squid was assuming a GETNEXT requests only a single object so it wouldn't
return a valid response.) The Net-SNMP agent was behaving correctly except
that it would crash upon receiving an invalid response from Squid.
The current problem seems to be purely misbehavior of the SNMP agent.
It's requesting objects over the proxy connection which are not below the
OID specified in the proxy config.
I'm in the process of trying to reproduce this behavior with my MIB
implementation
removed from the agent build.
