However, debugging process is very slow because I cannot reproduce the problem at all. ale@ is providing some core dumps and I am trying to figure out what's happening. I know some objects are getting free()'ed earlier than expected, which is ultimately causing SIGSEGV or SIGBUS *later*. So, I need more information. Please send the following information *privately*. grep -B 3 -C 8 CPU: /var/run/dmesg.boot cd /usr/ports/java/openjdk6 && make -V CC -V CFLAGS -V CXX -V CXXFLAGS In the mean time, it seems disabling background compilation (-Xbatch) significantly reduces chance of crashes as you already found out. Obviously, disabling JIT compilation (-Xint) should always work.
