Two weeks ago I re-installed my second DNSOnly nameserver. Both nameserver are clustered and are updated to the latest availabe CentOS and DNSOnly version. Since then CSF's daily log scanner report continues to show under /usr/local/cpanel/logs/error_log entries like this one

Code:
warn [cpsrvd] Previous check_sessions still running with pid: xxxxx.  Possible cpsrvd denial of service attack in progress. at cpsrvd.pl line 1141. cpanel::cpsrvd::script() called at cpsrvd.pl line 422
where the pid # varies.

The first nameserver was installed years ago running als the latest version of DNSOnly but without these errors.

I checked also for evidences of a denial of service attack. There were no suspicious activities.

Do you have any ideas what might be wrong?

Thanks
Sam

I see this quite frequently.
I've never gotten to the bottom of it, but it doesn't seem to cause me any issues.
