Slow Server performance !!

[mohankumar]

I have installed asterisk and vicidial, And it successfully throws calls .But the problem is the server is slow so that when the agent dispositions calls the call is still active and it drops after few seconds.Also all the agents are able to listen to the same call.

Even whwn the agent logins into the agent page he is getting the ring so late...

Please help me to solve the issue....

Sounds like you have a couple problems.

A. the server load is so high that it is taking a while for the line to hangup.
B. Your agents are logging into the same conference (this typically happens when agents do not log out properly).

Please provide the following information:

a. asterisk version
b. system load details
c. vicidial version
d. what kind of lines? ZAP/SIP/IAX2?

[mohankumar]

a.My asterisk version is 1.2.14 the version in the scratch installation
b.for testing we used 10 clients.
c.System configuration : P4 3Ghz ,1 GB RAM.
d.astguiclient 2.0.2b2 version.
e.SIP

Server works for two hours and then it slows down...We can see a Live call but it shows the Time out screen and asking us to disposition the call....

What is the loadavg when this happens?

[mohankumar]

LoaAvg on the system is 26.49

That's your problem, that lodavg is way too high, you need to get at least one more server to move some of that load off.

You can also switch your codec to Ulaw or use another machine to do transcoding for you.

[eijal]

And for timer what are you using?
ztdummy or any card?

[mohankumar]

I am using ztdummy card....Also i found that sox
is taking more CPU usage...
Should i remove sox package ?

[mflorell]

Are you recording ALLCALLS as well?

If so, you will want to modify your crontab settings to only run the mix_recordings script during off-hours.
