Dave,
I applied the zones patch last night to my copy of the source code and still
was having issues with it crashing. I downloaded the net-snmp 5.4.1 code this
morning and applied the diff-zones patch(bug 1794532) and the agent was dying
with the SIGSEGV error noted below.
I then went on and patched it with the code from bug 1792716
(diff.ipaddress-patch-541) and now it no longer dies but consumes 92 - 93 % of
the cpu and will not answer requests (One of the issues that I noted yesterday).
Now for the bad news. I cannot remove the duplicate IP addresses as thats the
way linux handles bonded ip addresses. They all show up but the two ethernet
devices which are bonded show up as slaves while the bonded device shows up as
the master.
GDB OUTPUT BELOW FOR OUTPUT PRIOR TO PATCH AFTER SNMPD Crashed.
