OS:
Linux TEST1 2.6.32.24 #1 SMP Wed Oct 3 14:51:26 CST 2012 x86_64 GNU/Linux
Hardware:
24 cores, 48G memory, 12G for heap.
The first time we saw this was after the server was shutdown abruptly (due to
the hardware issue). We have not seen the same issue for a while. However, it
happened again just a few days ago. Unfortunately, we could not find a
consistent way to reproduce it.
