Re: [SOGo] SOGo ActiveSync processes hanging in the same request

[Florian Unger]

With settings

    SOGoMaximumSyncResponseSize = 10240;
    SOGoMaximumSyncWindowSize = 256;

I still have the same issue.

Best regards

Hi,

all the topics I found on the net spoke about setting small values for sync to solve issues so I tried these settings:

  SOGoMaximumSyncResponseSize = 512;
  SOGoMaximumSyncWindowSize = 256;
which did not not help.

I will try your configuration with a large response size and see if that is doing the trick.

Thanks
Florian

Hi,

I am having some trouble with a small scale SOGo installation (less than 10 users) using SOGo 3.0.2 with ActiveSync and Outlook 2013 clients. I have SOGo configured for 15 workers and these are the ActiveSync specific settings I am using:

  WOWorkersCount = 15;
  SOGoMaximumPingInterval = 600;
  SOGoMaximumSyncInterval = 600;
  SOGoInternalSyncInterval = 30;
  WOWatchDogRequestTimeout = 6;
  SxVMemLimit = 768;
  /* Debug */
  SOGoEASDebugEnabled = YES;

After some time processes keep hanging in the same request until all workers are occupied and I get error "[WOWatchDog]> No child available to handle incoming request!"

At the end is an example of the log file of process 6808 and the last requests it got. I also made backtraces with gdb from that process (see attachment) - the process was either in function NGDescriptorRecv or in a sleep from SOGoActiveSyncDispatcher.

I tried increasing timeouts up to 1 hour as suggested in the Active Sync tuning hints from the manual, but that did not help. Processes were sitting just longer until they got killed by the watch dog.

Any hint how to resolve this issue would be great.

Best regards
Florian
