[App_rpt-users] ezstream 100% cpu

Thu May 5 03:00:30 UTC 2016

When the script runs you will find an indication in  /var/log/cron

Lines like this:

May  2 20:50:01 localhost crond[30559]: (root) CMD (/usr/local/sbin/./check_stream)

One thing that can cause a Linux system to grind to a near-halt is if you have run out of disk space ….

But I see you are running VBoxHeadless – I have no familiarity but a quick Google of that finds something related

Well my server is at it again 100% cpu usage for no reason kinda odd..

I did try Ken's script however I am not sure that its working the way it should...

I did place the info in crontab -e I wonder if we are missing some sort of dependency that isn't getting installed.. Maybe their is an easier way to broadcast to Broadcastify..

Here is an image of what it looks like this evening..

Ken, definitely confirmed on my last CPU spiking that lame's process was no longer running. I'll give your monitoring/restart script a try. Thanks for the info!

Of course the 100% CPU is probably due to it waiting for some resource, rather than actually being loaded to 100%. Press “1” in top and look for the “%wa”

I found (like some others) that the problem is actually the “lame” program which vanishes for some reason.  I run a script every 10 minutes that checks the pid for lame and restarts ezstream – but only if needed.  I think that is better than killing ezstream when it is, in fact, running fine.

This is the script (it is not my invention)

#!/bin/bash 

lamenumber=$(/sbin/pidof lame)

if [ "$lamenumber" = "" ]

then

        eznumber=$(/sbin/pidof ezstream)

        echo "$eznumber"

        kill -9 "$eznumber"     

        echo "restarting"

        date 

else

        eznumber=""

fi

Regards

Ken

A quick look at that cron schedule looks like it would run every minute of the 0 hour and 12 hour. Did you just want it to run only once at 0 and 12? If that is the case you'd want:

0 */12 * * *.

I'll let you know how it works out for stability. Thanks again.

The biggest issue with ezstream is that for some reason you get multiple instances of the program running.. Not sure exactly what would be the best solution to actually fix this but the cron script is a big bandage with duck tape.. I really wish I knew how to write code..

Thanks for the cron script to try Loren. Hopefully the daily restart of ezstream will cure any issues.

Here is what i did to get ezstream working I will be updating this forum as well as to my fix for ezstream locking open randomly basicly it kinda goes like this..

http://forum.kc9zhv.com/index.php/topic,23.0.html

crontab -e 

* */12 * * * sh /etc/asterisk/stopez.sh

script that i use to reset ezstream..

root at server:/etc/asterisk# cat stopez.sh

#!/bin/bash

kill -9 $(pgrep ezstream)&

sleep 2s

kill -9 pgrep ezstream

sleep 2s

/usr/sbin/asterisk -rx "module reload"

now to restart asterisk i run this customized script.

root at server:/etc/asterisk# cat restart.sh

#!/bin/bash

kill -9 $(pgrep ezstream)&

kill -9 pgrep ezstream

service asterisk stop

sleep 1s

killall asterisk

kill -9 $(pgrep ezstream)&

service asterisk stop

sleep 1s

service asterisk start

So far I have had no issues with ezstream since i did this..

Hello,
I've recently setup an allstar hub node and decided to stream it via broadcastify.

Setup has gone well - I'm running debian, with the allstar node running without issue, as well as streaming now being delivered via Broadcastify.

I've ran in to an issue where the ezstream process will occasionally pin at 100%. I can kill it fine, and asterisk gracefully resumes by creating a new working output stream.

Has anyone else encountered this cpu pinned usage? Will I have to set up something to monitor the process to kill it, so it restarts?

Thanks in advance for any suggestions

VA3BFW - Brent
