Multiple services stale in raw 2.0

Hi,
I’m experiencing the same problem, I have just installed from scratch this version: check-mk-raw-2.1.0p3_0.jammy_amd64.deb

I have 23 hosts and 746 services, I always have stale services that eventually get completed but there is always something stale.

The "Service checks: " values from performance never goes above 13/s

“cmk -vv hostname” lead to a valid check result
“cmk --debug -vvR” doesn’t give any error or warnings

I have also tried to change num_client_threads in ./etc/nagios/nagios.d/mk-livestatus.cfg from 20 to 80 but still the same problem

how can increase the volume of serice check per second? The CPU goes at maximum at 20%

@andreas-doehler @r.sander any idea?

Thank you

Here are the performance with all the server just restarted
just-restarted

Update: I have noticed that now the stale service are always the same 4 hosts that took about 40secs to complete the execution of the agent. While I was adding new host all the server systems seems blocked, maybe the cause was this stale services that was blocking also the pending service of new hosts?

If I change some rules for example I have 300 services in stale with a Service checks: of 7/s or 8/s
