I know about some problem with pthread async thread cancelation. I think its related to the jdk brokeness with linux2.6. I hope to finish all my SoC duties "soon" and spend the rest of the SoC time hunting down bugs like this. if anyone want help: www.vlakno.cz/~rdivacky/pthread.c this program does crashdumps with 2.6 emulation. I'd be very glad if someone can help me with this. I slightly investigated this and it crashdumps on signal delivery (pthread_cancel is actually a signal delivery) so I guess something with stack or so is wrong... havent had the time to investigate further help is welcome! roman
