Connector os cs and service are timing out

[lbi22]

We have multiple Windows instances in our company, but some of them are behaving weirdly. For a while, we haven't received any more metrics for some specific collector, more specifically, os, cs, and service.

Looking at the logs, it seems that they are timing out. I tried to increase the timeout with --scrape.timeout-margin=-20, but it didn't change. Here is an example of the output

.\wmi_exporter.exe : time="2024-02-20T23:53:07Z" level=warning msg="No where-clause specified for service collector. This will generate a very large number of metrics!" 
source="service.go:39"

I tried then to upgrade to the latest version of Windows Exporter,but the issue seems to be remaining, even though the only collector that is still failing is the service
