Is it regular to have the LUCOMS~1.exe and LuCallbackProxy.exe processes use a high amount of CPU when they're active? We've been running our SEPM server in VMWare for 6 months now, and whenever we do an audit of what servers use the most CPU, Symantec is always up there at the top. Whenever SEPM goes to Symantec to check for updates (I am assuming that's what LUCOMS/LuCallBackProxy are doing?), the CPU spikes. This occurs every 15 mins.
I hesitate to call it a problem, but I find it a little odd that our most CPU hungry server in the environment is SEPM, especially when we have SQL servers, Sharepoint servers, and virtual workstations for code testing also in the virtual environment.
I've attached an image to show you what I mean. You can see in the single-day graph that Symantec has regular spikes in activity. And if you zoom in on the spikes, you can see that our SEPM server is eating up the equivalent of 3GHZ of CPU for a couple minutes as LUCOMS/LuCallBackProxy are doing their things.
The virtual server that SEPM is running on a single virtual CPU, with 3GB of assigned RAM. We have approximately 150 clients locally to manage. Additionally we have a replication partner that manages 30 or so other PC's on the other side of the globe.
Several months ago I tried assigning the local SEPM server another CPU, but that made little to no difference.
Again, this isn't a problem per se, but I'd be interested in hearing some feedback about the two processes eat CPU cycles like delicious candy.
Note that the drop in CPU usage in the day-graph is me updating Windows, and restarting the server twice as per this thread suggested, just to see if that had any effect. (it didn't)
