EM Agent 13.4 oracledb.pl discovery plugin core dumps

Hello,
Unix team has been informing the DB team that certain VMs have core dumps on them every day, when the Auto-Discovery happens on our OMS 13.4 system:
/orasw/oma/agent/agent_13.4.0.0.0/perl/bin/perl
Here's the emagent_perl.trc error:
oracledb.pl: 2021-05-05 14:25:12,621: ERROR: executeCommand: /bin/srvctl config listener: cannot execute "/bin/srvctl config listener": No such file or directory
Looking into oracledb.pl, the command being run is $CRS_HOME/bin/srvctl config listener
CRS_HOME is only being UNSET at the top of the perl script if it's 10g. There's code for the rest of the setting of CRS_HOME. Can someone point me in the right direction of which setting is incorrect, or config file? The plugin is the same on a non-coredumping system, as this system that core dumps. I would think i'm looking for a config file that is wrong, or something.

Hello,
I would start troubleshooting this by analyzing the core dump file. My suggestion is to raise a SR for this and get the following:
1. strings <core dump>
2. get a core dump stack trace: TECH: Getting a Stack Trace from a CORE file on Unix (Doc ID 1812.1)

Thank you. I have an SR submitted and the Oracle Linux team is researching
