Can someone explain this?

restarting the solarwinds agent bring its back down to this

please dont tell me to change polling method the issue is the servers are spec'd out to do a task not then another 3rd of resource to monitor it.
Can I limit it somewhere or automate a service restart?
this is happening on about 20 servers that are close to the limits of the box's limits so is being highlighted.
Will probably be having this issue on other servers just not visable as they have more spec?
