Symantec Endpoint Protection Manager (SEPM) login hangs intermittently after upgrade to 14.0 MP1. During this hang issue clients gradually start disconnecting from the SEPM. Also the standalone reporting URL doesn't work.
Restarting the SEPM service fixes the issue, but eventually the issue comes back.
Windows Server 2012 Server Standard 64-bit
SEPM Version: 14.0.2332.0100
Apache performance issues.
Improve the Apache performance as below by tuning Apache for client communication and reporting component.
Edit the httpd.conf file, increasing the value for "ConnectionsToQueuePerChild" from '500' to '3000', as it was with 12.1.
Reduce the TIME_WAIT socket connection numbers if you see a buildup of TIME_WAIT connections in the log. TcpTimedWaitDelay Registry value: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\TcpTimedWaitDelay Value Type: REG_DWORD Data: 30 (decimal)
MaxUserPort Registry value:HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\MaxUserPort Value type: REG_DWORD Data: 65534 (decimal)
Throttle the agent registration by adding the following 3 parameters in conf.properties file: scm.agentregistration.throttle.low=5; scm.agentregistration.throttle.high=10; scm.agentregistration.throttle.leak=100;
Reduce the objects cache by adding the following to the conf.properties file: scm.cache.thereshold=600
If possible, reduce the Liveupdate frequency on the SEPM and increase the heartbeat interval of all the groups.
