Hi there, I run into issues while running 8 clients + 1 data node on a single machine (Macbook Pro 16GB RAM). I get pretty weird JVM errors. [thread 167427 also had an error] # # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x000002018b9d8c29, pid=10278, tid=167171 # # JRE version: 7.0\_21-b12 # Java VM: Java HotSpot(TM) 64-Bit Server VM (23.21-b01 mixed mode bsd-amd64 compressed oops) # Problematic frame: # C 0x000002018b9d8c29 # # Failed to write core dump.

If you still have the stack traces of the threads in hs\_err\_pid10278.log, you should consider to post it for analysis (or to bother Oracle with it).
