Since upgrading vlogger to v1.9, I had a strange phenomena: The apache workers got eaten up even in idle times.
Checking the apache server log, I saw hundreds of those entries:
Interestingly, since the connect sting was not mis-configured. If mis-configured, vlogger would complain on start up and turn the feature off:
Checking vloggers line 494, leads me to the sub routine dumpTracker's connect string:
I replaced the hostname with the server's IP address in /etc/imscp/apache/vlogger.conf and it works. I do not know, why this connect string is not working with domain names (anymore).
Two things should be done now:
1) fix the error string
2) close open sessions to avoid workers getting eaten up
