Change the if line to:
+ if ((timer_status.it_value.tv_sec == 0) && (timer_status.it_value.tv_nsec == 0L)) {
+ ast_debug(1, "Reading attempt on idle timerfd.\n");
+ return;
+ }
Does the performance degrade then also?
This is part of my submitted patch https://issues.asterisk.org/jira/browse/ASTERISK-17867 (res_timinig_timerfd_read_deadlock.patch)</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Actually, I mean "yes, regretfully" to the question "Does the performance degrade." For some reason I had a bit of a disconnect between what you actually said and turned it into "Does this fix it"</pre>
