libresip segfault at 1160 on 3CX 16.0.619

[tomg]

Hello

I have a problem with 3CX crashing several times a week, sometimes a day. All crashes occur with the same segfault message:
3CXPhoneSystem[21337]: segfault at 1160 ip 00007ff1304e9ac0 sp 00007ff1077fd1f8 error 4 in libresip-1.10.so[7ff13037b000+24d000]

The server is in a virtual machine on VMWare. Output of uname -a is
4.9.0-4-amd64 #1 SMP Debian 4.9.65-3+deb9u1 (2017-12-23) x86_64 GNU/Linux. The 3CX version is 16.0.619, no updates available.

I have:

1. Switched from vmxnet to e1000 NIC as suggested here: https://www.3cx.com/community/threads/3cx-v15-5-15502-6-sip-server-crashing.66650/post-286648
2. Patched the systemd files to restart the services upon failure

Point 1 had no effect.

Any thoughts?

Version: 16.0.619 (Professional Perpetual)
Server OS: Debian GNU/Linux 9
Hosting: Own VMWare host running on a cloud server
Phones: Mix of 3CX softphones (on Win 10 and Android) and a GrandStream GXP2130
Firewall checker: OK

The environment is working otherwise, we have at the moment 133 extensions up.

 

[Saqqara]

How many processors, and amount of memory assigned to the Debian virtual machine

Have you thought about increasing the memory as a test ?

 

[tomg]

Thank you Saqqara for the reply.

This is what ESXi says:
CPUs 2
Memory 2 GB

I will up the memory

@Saqqara recommendations are spot on. Please review this:

https://www.3cx.com/docs/recommended-hardware-specifications-for-3cx/

For 133 extensions you fall between the medium and large range. 3CX recommends 4 vCPUS/4 GB of memory for medium and you have 2/2
