Cannot start 3CXPhoneSystem - segfault

[yetopen]

Hi.
Today I wasn't able to use my 3CX app, so I logged into the console and found CallFlow server stopped. It wouldn't start so I tried upgrading, maybe it was a fixed bug... Now I have 16.0.5.612 (was 16.0.5.611 before) and not even 3CXPhoneSystem will start!

```
May 11 14:40:56 tel systemd[1]: Starting 3CX PhoneSystem 01 SIP Server...

```

I didn't change anything recently. The only change was the trial Pro which expired over the weekend and it's now a Standard.

Host is a Debian 9.12. I tried purging and restoring the backup but it's still crashing.

Callflow requires Pro or Enterprise license

Can you remove the CallFlow settings via the management console

Ok but it's not starting at all now!

Hi,

It's best to start from here and provide all the relevant information about your instance
https://www.3cx.com/community/threads/information-to-provide-when-requesting-help.67558/

Don't forget to mention your network setup, how the PBX connects online and how many NICs you use or if you use a VPN.

I found the culprit: I had installed OpenVPN client to link the remote cloud server to the office net. As soon as the VPN starts 3CX crashes:

So is there any workaround to avoid sefgault when OpenVPN is enabled? Thanks

Look at the Pre-requisites - no other software to be install on the 3CX this includes any vpn software

Someone my have a work around

OpenVPN is not supported for running on the PBX.

However, if the PBX is not the endpoint, you should be able to have a VPN. Perhaps another machine can take care of the VPN part, acting as a switch/router, to which the PBX will eventually connect to.
