High CPU usage from Httpd.exe on a Symantec Endpoint Protection Manager
On a Symantec Endpoint Protection Manager (SEPM), the Httpd.exe process consistently uses between 40 and 60% of the CPU resources.
No Transmission Control Protocol (TCP) traffic is displayed in a netstat output.
CPU usage lowers and the netstat tool displays TCP traffic correctly when the SEPM services are stopped.
Symantec is aware of this problem and will update this document when a solution becomes available.
