Zabbix Proxy crashing irregulary. It's always because of preprocessing manager. Most of the time the proxy is able to exit completely and restarts. But sometimes the proccess freezes and has to be killed (-9) and restarted manually.

Red Hat Enterprise Linux Server 7.9 (Maipo)
Linux <redacted> 3.10.0-1160.59.1.el7.x86_64 #1 SMP Wed Feb 16 12:17:35 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
Zabbix Proxy PostgreSQL v5.0.23 from repo.zabbix.com.
It happened with several other older 5.0.x versions too.

I've attached a log containing 5 crashes. The last two did not restart automatic.

Might be related to ZBX-20888.
