and how is the acl rubios defined?

More GDB commands:

frame 1
print *list->acl
print *list->next->acl
frame 4

and did you get any messages in cache.log when it crashed?

but so far it looks like Squid failed to process a SNMP packet and then
crashed in access controls. As a temporary workaround, please change
snmp_access to have the ACL's listed the other way around.

snmp_access allow rubios snmppublic

This way only packets matching the acl "rubios" will be allowed to crash

I usually do not use any snmp_community acls for SNMP access controls,
but then I have my snmp port bound to only listen on the loopback
interface.. (, and no user accounts on the proxy server..
