    POSIX timer failure


    Hi, I'm using the POSIX timer functions (timer_create, timer_settime) to
    manage comms timeouts and, under SLES 11, I'm hitting some problems.

    Basically, I create a first timer then create and delete a number of
    other ones before the first timer times out. When it times out, the
    timeout function doesn't appear to be called and the next timer_create
    call hangs up indefinitely (see attached code*). The code works fine on
    SLES 10.

    Attaching a debugger, I can see that the timer_create call hangs up in
    pthread_mutex_lock after the first timer has expired.

    Anybody any ideas? Am I abusing the timers? Has something changed in
    the semantics at SLES 11?

    Thanks
    Phil

    Re: POSIX timer failure


    My intermittent researches into this have revealed this bug, which might
    be pertinent.'Bug 7094 - Bug in creating/deleting posix per process
    timers with SIGEV_THREAD notification method'
    (http://sourceware.org/bugzilla/show_bug.cgi?id=7094).

    How can I tell if this has been addressed in SLES 11?

    Thanks
