I do have use_large_installation_tweaks set to 1.  We have a very large 
installation and will need this eventually.  I've been running valgrind 
overnight with embedded perl and have had no issues.  The only thing it 
reported were the few startup leaks.  Looks like the embedded perl is at 
fault here.  Thanks for the help.

I'm not sure what embedded perl will gain us but most of our checks are home 
grown perl checks.  We were getting latencies in excess of 300 seconds on 
nagios 2.x so we were looking at anything we could do to speed up the 
process.  Looks like embedded perl is out for now.
