If you experience FS crashing IraDialer deployments please check and confirm the following:
1. What is the call volume being handled by the servers, this is the total calls that are handled by the server including conferences. You can refer to IraDialer dashboard to get these details.
Refer to "Calls" column under Load Balance Stats.
2. Is the server specs sufficient to handle the call volume. For Debian instances, we suggest 80 calls / core, but on Windows it may be slightly lower considering the Windows OS overhead. On many deployments a 2 core server was being used which is not a suggested specs for Windows.
3. Between the time period of FS crashes have you collected all the component logs.
4. Are there any playurl APIs being used where those files are not accessible by IraDialer servers. We have encountered this in multiple deployments where curl request to access the mp3 file was failing from IraDialer servers.
Please search for "Error opening" word in all the freeswitch.log files.
5. Are IraDialer APIs being used to conference the customer calls with IVR(voicemail feature).
