hi we are facing exactly same problem as described in but on a physical machine: Thread.sleep() is hung?
machiry@pag02:~$ uname -a Linux pag02 2.6.32-5-amd64 #1 SMP Mon Jan 16 16:22:28 UTC 2012 x86_64 GNU/Linux
machiry@pag02:~$ java -version java version "1.6.0_26" Java(TM) SE Runtime Environment (build 1.6.0_26-b03) Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)
any help would be greatly appreciated.
