Post Zabbix server upgrade 6.2.4 to 6.2.7 getting more alerts

[scase]

I have 2 Zabbix servers. 1 is a larger box acting as the main monitoring server. The second one is a smaller box that is basically just to let us know if the primary goes down and also as a testbed for trying things out.

I updated both systems over this past weekend (6.2.4 to 6.2.7). Everything seemed fine for 2 or 3 days. Then we started getting quite a few more alerts. A fairly big percentage of the new alerts were messages about the Zabbix servers:

Zabbix server: Utilization of lld worker processes over 75%
Zabbix server: Utilization of escalator processes over 75%
Zabbix server: Utilization of configuration syncer processes over 75%
Zabbix server: Utilization of availability manager processes over 75%
Zabbix server: More than 75% used in the history cache

I normally would assume that I just need to address the configuration and all would be well again. Unfortunately, this doesn't seem to be the case. I'm getting these alerts from both servers, even though the smaller one is only monitoring itself and the primary server.

Has anyone else seen this behavior? I'd rather not have to revert back, but I'll do it if i need to.

Feel free to let me know if I need to clarify anything.

Thank you for any input anyone has.
