Core dump for snmpd
Description of problem:
After upgrading to the latest release of the net-snmp package the service will fail after some time with the following error in the journal.
Jun 27 12:27:35 node1 snmpd[10056]: NET-SNMP version 5.8
Jun 27 12:43:53 node1 snmpd[10056]: double free or corruption (fasttop)
Jun 27 12:43:53 node1 systemd[1]: snmpd.service: Main process exited, code=dumped, status=6/ABRT
Jun 27 12:43:53 node1 systemd[1]: snmpd.service: Failed with result 'core-dump'.
Version-Release number of selected component (if applicable):
net-snmp-5.8-7.el8_0.1.x86_64
How reproducible:
Always.
Steps to Reproduce:
1. Install the package
2. Start snmpd service
Actual results:
Service fails with error message.
Expected results:
Service runs with no errors.
This issue is already resolved by bug #1694047.
Fixed version of net-snmp (net-snmp-5.8.8) will be available in RHEL-8.1 release.
For testing purposes, you can use following build [1].
Due the issue is already solved, I am closing this report as CURRENTRELEASE.
[1] https://brewweb.engineering.redhat.com/brew/buildinfo?buildID=892992
I have tested the scenario from #02415022 on f30 (net-snmp-5.8-10) and RHEL8 (net-snmp-5.8-10) and all is working for 90+ minutes as expected.
I have used the /etc/snmp/snmpd.conf file from attached SOS report and I am not hitting any issue with net-snmp.
Can you share more information about what queries are sent to snmpd (snmpget, snmpwalk and so on) via #02415022?
(Copied from Fedora bug report)
After further testing, it looks like I'm only getting the failure when using v3. Once I switch the monitoring system to use v2c, I no longer get any service crashes/coredumps.
While this is a workaround, we would prefer to use v3.
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
resolution of ERRATA.
