memory leaks

I've been experiencing a pretty consistent memory leak with 4.5.2, build 2244. I have to restart every 4 hours or so. I'm not sure if it's the build, or possible one of the plugins I have installed.

I was curious if anyone else was experiencing this, or had isolated it to a plugin. Here's my plugin list:

file status bar
hibernate
Jboss (but not using it currently)
JProfiler
KiwiScrap
LineMover
MetricsReloaded
PropertiesEditor
Rearranger
RegexPlugin
SequencePlugin
simpleUML
SmartIntroduce
SQL Query Plugin
TabSwitch
XPathView

However I only use these actively:
File status bar
RegexPlugin
SmartIntroduce
TabSwitch

Ring any bells?
