--- Comment #1 from lakagwu at redhat.com ---
Workaround is to set ConcGCThreads to a value less than or equal to the number
of available cores.
When CMSConcurrentMTEnabled is set and ConcGCThreads is unspecified,
ConcGCThreads defaults to (ParallelGCThreads + 3)/4)

Bug is fixed in 

java version "1.6.0_27-debug"
OpenJDK Runtime Environment (IcedTea6 1.13.0pre) (linux-gnu build
1.6.0_27-debug-b27)
OpenJDK 64-Bit Server VM (build 23.7-b01-jvmg, mixed mode)
