I am trying to add SOGo to an already working server with Postfix + Dovecot.
The server is Centos 7, 2 core with 3Gb RAM with less than 10 users. Sogo installed from official repo: sogo-2.3.8-1.el7.centos.x86_64 Sogo is configured with 10 workers with this configuration: WOWorkersCount = 10; WOListenQueueSize=10; WOWatchDogRequestTimeout=60; SOGoMaximumPingInterval = 354; SOGoMaximumSyncInterval = 354; SOGoInternalSyncInterval = 15; SOGoMaximumSyncWindowSize = 50; SOGoMaximumSyncResponseSize = 2048; The problem is SOGo processes starts eating all the RAM and sometimes hangs. The log file reports: Feb 19 13:30:26 sogod [13164]: <0x0x7f1357056030[SOGoActiveSyncDispatcher]> Sleeping 15 seconds while detecting changes in Ping...
