I've got a report that agents on Windows are randomly stopping after some time running. It can be a month after the agent started. Windows versions vary, so there is no common ground in Windows versions.
The only message logged is this:

...

2024/06/20 15:30:53.146021 Detected performance counter with negative denominator the second time after retry, giving up...
2024/06/21 02:41:45.172180 Zabbix Agent 2 stopped. (6.4.2)
2024/07/17 15:23:17.850481 Starting Zabbix Agent 2 (6.4.2)

I have instructed user to upgrade agents to 7.0.1 when it comes out, and increase debug level to 5 for one of the agents which stops. Will provide debug level logs when it happens.

As a temporary workaround, user implemented automatic restart on service failure on Windows level.
