I now also did packet captures on both ends (device/cacti server) and I see the conversation is identical, no sent packets that didn't make it back to the cacti server, rather the server, snmp requester if you like just decided to timeout without sending the next get-request after the last get-response. 16 requests 16 responses on both captures.
As these happen on a specific segment of the tree I narrowed down my snmpwalk request so it's just in that area so that it'd take a minimal amount of time and data (32 packets..) Can there be anything that would interrupt net-snmp's connection? 13.06.2014, 13:03, "chris tech" <chris.t...@yandex.com>: > Hello all, > > Release 49.el6_5.1 on CentOS (2.6.32-279.9.1.el6.x86_64).
