This SMP 5.3-STABLE system updated yesterday acts as a resolver for a
bunch of package clients. I just got this message in the logs:
Oct 25 01:45:00 <daemon.warn> pointyhat named[281]: *** POKED TIMER ***
This comes from contrib/bind9/lib/isc/timer.c:
/*
* This is a temporary (probably) hack to fix a bug on tru64 5.1
* and 5.1a. Sometimes, pthread_cond_timedwait() doesn't actually
* return when the time expires, so here, we check to see if
* we're 15 seconds or more behind, and if we are, we signal
* the dispatcher. This isn't such a bad idea as a general purpose
* watchdog, so perhaps we should just leave it in here.
*/
if (signal_ok && timedwait) {
isc_interval_t fifteen;
isc_time_t then;
isc_interval_set(&fifteen, 15, 0);
isc_time_add(&manager->due, &fifteen, &then);
if (isc_time_compare(&then, now) < 0) {
SIGNAL(&manager->wakeup);
signal_ok =3D ISC_FALSE;
isc_log_write(isc_lctx, ISC_LOGCATEGORY_GENERAL,
ISC_LOGMODULE_TIMER, ISC_LOG_WARNING,
"*** POKED TIMER ***");
}
}
and suggests it could be a threading bug.
