我正在尝试使用Postfix + Dovecot将SOGo添加到已经正常工作的服务器中。
服务器是Centos 7,2核心，3Gb RAM，用户少于10个。 Sogo从官方仓库安装：sogo-2.3.8-1.el7.centos.x86_64
/ etc / sysconfig / sogo为10名工人设置：PREFORK = 10“
Sogo配置了10名具有此配置的工作人员：
WOListenQueueSize=10;
WOWatchDogRequestTimeout=60;
SOGoMaximumPingInterval = 354;
SOGoMaximumSyncInterval = 354;
SOGoInternalSyncInterval = 15;
SOGoMaximumSyncWindowSize = 50;
SOGoMaximumSyncResponseSize = 2048;
问题似乎是有效的同步客户端（ms outlook）。 SOGo进程开始吃掉所有RAM并且有时会挂起（进程不能被信号15杀死）。该问题似乎与日志文件报告有关：
