    Depending on the TCP/IP implementation on HPUX, you might get a SIGPIPE
    from a broken TCP connection. Try adding this to your signal handler,
    but it depends highly upon the underlying ORB which does the network
    handling if this will get you further.

    Catching signals like SIGSEGV or SIGBUS is of limited value, unless you
    can be sure that your thread is either destroyed/cancelled without repeating
    the faulty access *and* the variable/member in question is released or
    overwritten. But I am repeating myself....

    HTH,
    Uli
