Issue:
In some user cases, log monitoring settings mainly create 'problem' events only,
Users' log settings might only 'problem' events, causing a over too many unresolved problem entries (5M+)
This can slow the SQL affect and make the Zabbix UI not work properly.

Suggestion:
We should advise keeping the problem table clear by resolving/closed events.
We could monitor the count of unresolved problems in the table and with warnings in the System Information. (it could be risky if there are over 1M records.)
Providing a bit of guidance on adjusting settings could prevent such setups.
