I am wondering if the following warning in the SOGo log are anything to worry about:

Sep 15 15:46:32 sogod [19786]: <0x0x5582bfb7be40[SOGoActiveSyncDispatcher]> Sleeping 30 seconds while detecting changes in Ping...
Sep 15 15:46:39 sogod [19780]: [WARN] <0x0x5582bf6ee3d0[WOWatchDogChild]> pid 19794 has been hanging in the same request for 9 minutes

I see the same type of warnings over and over again. Is it normal for a SOGo pid to hang for multiple minutes?
Is there a variable that I need to adjust? Earlier today SOGo was running out of processes so I increased PREFORK and that seems to have resolved that problem but I am wondering about the other warning.

Regards,

Tom
