noderunner.exe consuming too much memorhy

Hi

I have run by mistake following command

Get-MessageTrackingLog -Server Mailbox01 -Start "10/28/2016 09:00:00" -End "12/18/2015 17:00:00" -Sender "user@domain.com" | Out-GridView

After this noderunner.exe started using too much memory and at this point i cannot do anything  server is almost out of memory. Is it safe to terminate this process noderunner.exe so that i can get memory back.

I wanted to search tracking log but it was apparently mistake.

Any way to quickly recover from it
