Also Mem Usage in Windows Taks Manager is really huge, more than 1.5GB (of course, depends on machine)

EVALUATION Handle leak is IE7 related. Disabling Phishing filter in IE7 should fix the handle leak. The following are related patches for IE7 KB955478 Phishing Filter situation with Internet Explorer 7.0 KB956625 Microsoft Text Services situation on Windows XP and Windows Server 2003.

EVALUATION I've tested with jre 6u2 promoted build and couldn't reproduce the OOM error. Both thread and GDI objects counts remain pretty much the same after a 14-hour run. However, the handles count and the memory usage increaes quite a lot. Data as follows: mem use (KB) handles threads GDI objects start 54060 914 34 539 after 14hrs. 871404 20774 33 578 So some investigations is still need for the increase in handles an memory usage in jre 6 update. I'm marking this bug as mustang-na since there's no OOM error with 6u2 but leaving it open for continue investigation on the handles and memory leak.
