After removing default filters from the profiling tool, it was revealed 
that the work that is being done every ~20 seconds and lasting for 8-10 
seconds includes the following functions via the updated thread dump 
<http://i.stack.imgur.com/NAmc5.png>:


   - java.io.WinNTFileSystem.canonicalize0 (6-8 seconds)
   - java.io.WinNTFileSystem.getBooleanAttributes (inFile.exists()) (~1 
   second)
   - StardardRoot.java (~1 second)

Is there a reason DSpace would launch a check like this every ~20 seconds? 
Or could Tomcat have a reason to launch something to find out if a file 
exists?

A contributor on Stack Overflow discovered that curated tasks could be run 
on a schedule -- is there a way to disprove a DSpace scheduled / periodic 
task is running? When I ran a test curated task it appeared in the 
dspace.log file but no updates to the logs have happened in the last hour 
and yet the periodic spikes are still occurring.

(Stack Overflow 
<http://stackoverflow.com/questions/34138850/what-would-cause-tomcat-v8-to-cpu-spike-with-periodic-regularity)>
 
was updated as well.)
