New Revision: 193718

URL: http://svn.asterisk.org/svn-view/asterisk?view=rev&rev=193718
Log:
Fix some timer state corruption.

In res_timer_timerfd, handle the case that set_rate gets called while a timer
is still in continuous mode.  In this case, we want to remember the configured
rate, but not actually set it until continuous mode has been disabled.

Thanks to dvossel for finding and helping to debug the problem.

(closes issue #15080)
