Hi Ole, It looks like that offending code wasn't removed, it was just relocated further along [1]. Looking at what they have done for net-snmp 5.9.2 snmplib/snmp_api.c isn't changed between 5.9 and 5.9.2 so I'll apply it as the problem isn't going away.
Your bug report was fine BTW. If there was an easy proof of concept that is even better but this looks like its a timing issue with delayed responses. The information helped get a resolution for me pretty quickly. - Craig 1: https://github.com/net-snmp/net-snmp/blob/V5-9-patches/snmplib/snmp_api.c#L5772
