Description

SHL4 C3 QTISCS223sp4实时报警每天约慢1秒-1周约慢5秒
重启平台后,调度客户机实时报警插件1秒内实时显示变位报警记录
经过一周后,变位报警,实时报警插件慢5秒,时间越长慢的越厉害
20210830现场再次排查,发现1#dac服务器=主域控 给节点发送公告牌广播慢
检查计算机资源消耗,CPU64逻辑核,每个单核都占用很少,内存32G,占用4.7G
后尝试切换主域控到其他2#dac服务器、1#daq服务器、2#daq服务器、各调度工作站,
结果,非1#dac服务器=主域控 时,报警都是1秒内在客户机上报;只要再切回1#dac服务器=主域控,客户机报警插件就变回慢3秒了
当前,按2#dac服务器=主域控,运行一周后再观察一下。
如果不再出现报警越来越慢,则暂时认定1#dac服务器本身设备或操作系统问题
