Asterisk 17.8.1 not releasing RTP ports

Asterisk Asterisk SIP

Hi,

I’m running multiple asterisk containers on a host and after few days of running, we are experiencing an error “res_rtp_asterisk.c:3798 rtp_allocate_transport: Oh dear… we couldn’t allocate a port for RTP instance ‘0x7fa6c0384d20’”

asterisk -rx “core show channels count”

139 active channels
70 active calls
3062854 calls processed

I don’t think anyone here will invest time in a 2+ year old unsupported version of Asterisk. Noone has reported such an issue in current supported versions.

Hi jcolp,

Do you have any idea why it shows multiple asterisk execution.

ps -aux |grep /usr/sbin/asterisk

You stated “I’m running multiple asterisk containers on a host” therefore multiple Asterisk instances would be running. Unless you mean something differently.

6

It shows single process after restarting the asterisk service, but it keeps increasing day by day. I also found that it releases the rtp ports if i kill all the asterisk processes except the one asterisk running on.
in this case pid = 16052 is the main.

7

The fact remains that you are using an expired version of Asterisk and need to reproduce this on a current version.

8

I suggest you give rather more detail regarding what “I’m running multiple
asterisk containers on a host” from your first posting really means.

Otherwise we are only guessing about the setup you are running.

Antony.

I have four containers running with Asterisk 17 each. One of the containers shows multiple Asterisk processes, such as “/usr/sbin/asterisk,” with 15 processes. When I manually kill all of these processes, the RTP ports are released.

For example, if I kill all PIDs except for the one I highlighted, it frees up all of the RTP ports.

I’d want to know what process 16052 was.

11

This is the main process id since the Asterisk service started running. I just want to know from where the other pids came in and why those processes were not releasing rtp ports.

12

The main process ID of what?

Why is the process that is actually consuming CPU not a child of that process?

Also, my understanding is that using Asterisk under Docker is not a supported configuration, so you are at your own risk.

13

The main pid of an asterisk, as you can see in the screenshot.

14

Apologies. I missed that.
