Using JBoss' TreeCache and its clustering technology, that uses TCP, UDP and Multicast sockets. Mustang crashes with a SIGSEGV on a SLES 9/64bit machine.

The same code
- works fine with Java 1.5.0_07(64bit) but
- fails with SIGSEGV using Mustang/64bit (b83, b90 and b92) and
   stderr:
   *** glibc detected *** free(): invalid pointer: 0x0000002b005e4ab0 ***
   (core dumps here..)
- gives glibc warnings with Mustang/32bit (b92):
   stderr:
   *** glibc detected *** double free or corruption (fasttop): 0x08812ab0 ***
   *** glibc detected *** free(): invalid pointer: 0x08812b38 ***
   *** glibc detected *** double free or corruption (fasttop): 0x08812a90 ***
   *** glibc detected *** free(): invalid pointer: 0x08812a40 ***
   *** glibc detected *** double free or corruption (fasttop): 0x0877b580 ***
   *** glibc detected *** free(): invalid pointer: 0x08812a88 ***

Attached the hs_err*.pid file from Mustang-b92/64bit to this email.

Had tried several JVM options (-server / -client / -Xms/mx / -Xint / -XX:+UseParallelGC ) but all resulted in the same SIGSEGV.
