Looks like your SOGo configuration is under-sized.
How many EAS client do you have connected to SOGo?
For 10 devices I suggest you this configuration

config setprop sogod WOWorkersCount 15
config setprop sogod SOGoMaximumPingInterval 3540
config setprop sogod SOGoMaximumSyncInterval 3540
config setprop sogod SOGoInternalSyncInterval 30
signal-event nethserver-sogo-update

I actually run after the setup you describe. There are four EAS clients
