op_server.pl taking maximum cpu time.
Submitted by shishir on Sun, 11/18/2007 - 3:47am.
hello everybody,
After tracking the system i figured out that op_server.pl is taking max. cpu time. More the call in the queue more will be the load. I have attached the output of top as below.
top - 14:28:47 up 20 min, 4 users, load average: 3.05, 2.48, 1.44e

Hi
I also have the same problem, my pbx has been misbehaving, it freezes such that calls stop coming through and it stops working. Been monitoring cpu usage & also noticed that op_server.pl causes considerable load on cpu. Did u find a solution to your problem? Please help me out.
Thanx!

Hi,
The op_server.pl runs

Hi,
The op_server.pl runs the script to show the calls status on the flash panel which leads the system uptime to be high if there is large number of extensions say 170+.
As for my case i solved the problem by load balancing i.e separated the total extension into two different server. You can also stop the op_server.pl by command "amportal stop_fop" this will stop the op_server.pl to get load.
If this solution informative, do comment..

Does stopping op_server.pl

Thanks for the response.
Before I try your suggestion, will "amportal stop_fop" stop showing the call status on the pbx PANEL web interface? I would still need to monitor calls using the panel. You also mentioned that system uptime will be high if there is large number of extensions say 170+, I only have 35 extensions and may add on five new ones. Maybe my load is also high because the pbx is for a call centre so phones are constantly ringing.
No amportal stop_fop will

No amportal stop_fop will stop the flash panel on web interface. You can also try the alternate way to configure the system which might help to reduce the system uptime.
Will you rite the detail configuration of your system and the number of zip/iax/zaptel channels you are using !! that will help to debug the problem !!!

Am still new to asterisk,
Tue, 04/15/2008 - 2:32am
Am still new to asterisk, are there any specific files you want information on as far as the configuration is concerned? Not too clear on which configuration details you want. I have 16 zaptel channels and 35 extensions. I tried using "amportal stop_fop" and observed the following:
1)httpd process startred coming up, at times 2 of them at one time each using on average 17 -20% cpu
2)there was no significant change in performance,
3)today for some reason asterisk is now showing 100-110% cpu, usually its 10 -15% cpu, didnt
change anything except "amportal stop_fop" & "amportal start_fop"
4)even after "amportal start_fop" the httpd processes were still appearing frequently
Below is output from this morning show the high asterisk cpu %:
Below is the output I get when monitoring cpu usage, you'll notice that asterisk shows 105% usage and op_server shows 17% but at times the op_server.pl can be as high as 41% or 67%:
