As an admin user, you can click on 'Jobs' in the top right hand corner of the UI and see all searches that are currently running
And in Windows you can look in the Task Manager (or use Process Explorer, or whatever) and look for instances of splunk-search.exe
If you are running Splunk on Linux you can also execute "ps -ef | grep search" from the command line.
But that only applies to Splunk 4.
To add on to this comparison: the splunk-specific monitoring does know more about the searches, but the operating-system level inspection is an intended feature. If something is misbehaving, we want the tradiditional tools to be informative. renicing jobs is kosher, as is a goold old SIGQUIT, in a pinch. The windows equivalents should also be fine.
That would certainly work, but you jobs tab in the ui gives the percentage complete. So, you could just watch the search finish before restarting, instead of rerunning ps.

In splunk 6, "Jobs" is under the "Activity" heading.
