I have prepared scratch build with possible solution. @pavel Are you able to test it on your case? Scratch build: https://koji.fedoraproject.org/koji/taskinfo?taskID=37736050 5.8-13, fc30: snmpd daemon do not crash, command line tools work as required but now i see problem with perl module SNMP::Session i have test table with 2000 records, snmptable fetches all rows, SNMP::Session::get_table stops after ~127 rows with status: (genError) A general failure occured (tooBig) Response message would have been too large. can successfully retrieve the same table under fc28 This issue also appears to affect RHEL/CentOS 8. The snmpd service crashes every few hours with log entries similar to below.
Dec 30 01:25:39 host.example.com systemd-coredump[788]: Process 30476 (snmpd) of user 0 dumped core.
