1.8b Development

So, I am running 1.8.1b540 in production.  And noticed the memory utilization is a tad high at 75%.  So I did some digging...

Code:

$ top -d1
last pid:  4164;  load averages:  0.24,  0.19,  0.12  up 43+14:53:53    12:55:40
17 processes:  1 running, 15 sleeping, 1 zombie

Mem: 647M Active, 6812K Inact, 55M Wired, 28K Cache, 13M Buf, 239M Free
Swap:

I have not had a chance to reboot and see if it is repeatable, and I do need to upgrade, but has anyone else seen this?
