Zabbix known issues have announced a crash of Oracle 11.2.0.4.0 client.
But this crash error has been reported on client usage 19.11(RHEL8), 19.13(AmazonLinux2), 21.1
As a workaround, I have stopped ODBC and using a Zabbix Agent2.
Created to issue a check and investigate error cases like this one. The cause is unknown, but It could also be a version issue like ZBX-18402.
