Best Timing Source? (Carlos Chavez)

Hi Carlos

We had similar issues with Asterisk and Asterisk with timerfd and pthread timing.

The server instance would run for 20 or 30 minutes and then producde legions of error lines about timerfd or pthread, whichever we were using.

The symptoms were voice quality issues – jitter and packet drops spiked alarmingly during periods where these errors about timterFD and pthread were being emitted.

This was also on CentOS 7.

The solution in our case was two fold.

– We switched from Asterisk to Asterisk

This was step one – since when we used timerfd or pthreads with
(even though it was much newer than we STILL had the problem.

– I am starting to think that the problem may be in the server hardware itself. We are using a Dell R220 with 8gb of ram and 2 hard disks in a Raid 1 configuration (Linux Raid). We are using CentOS 7. We had to remove the raid card from the server to install an E1 card (the raid card was Windows only so no loss there really). Internally everything sounds good (from E1 to a conference or music) but once you hit a network interface we start getting pops and drops.

Anyone with this server and Asterisk ever had issues like these?
