Hi,

I'm running FusionPBX 4.4 and have recently starting getting the following message:

[ERR] switch_cpp.cpp:48 Cannot queue any more events



This system system load is quite low max 20 calls per second and max 60 calls, hosted on AWS (very low CPU and RAM utilization)


I've read on other posts that the issue here would be with a script that is consuming events but not processing them quickly enough. I'd like to get pointed in the right direction to track down what script this might be, is there some debug or logging mode I can enable to track this down?


Thanks.

your dialer script is probably not fast enough to handle the events is monitoring.

fs_cli is the place to start. I will show the exact line of the code that's reporting the issue. You can then look into the code to see what might be going on.

Hi Ken,

We are using FusionPBX just as a business phone system so utilization isn't too high at all. There are many users of FusionPBX with much much higher loads than me and they don't experience this issue. Any tips on tracking down the script that may be causing this?

Also note the following:

This ERROR takes a couple of weeks to appear after rebooting the system.
When the error occurs it doesn't seem to affect the performance of the system at all.

the script thats originating the calls. 20cps at a mac of 60 concurrent calls can only be dialer traffic. (20cps is enough dialer traffic to light up almost 200 ports of dialer or several hundred ports of conversational traffic)

If its pure Fusion I would contact their dev to as Fusion configs while they are running on top of FS add a bunch of things that is FusionPBX specific

Thanks for the response Ken. I was getting the 20cps from the show status command (see below). I always thought that was because I have a couple of clients with large ring groups 10-15 extensions in a ring group. With the clients I have it's very unlikely that would be making too many outbound calls. One last question for you though Ken, if I see this ERROR and it doesn't seem to have any effect on the the performance or functionality of the system, do you think I could safely ignore it for now until I upgrade from to the latest version of freeswitch (and fusionPBX)?
