Server Error while trying to log into management console. Among other problems.

[lkjencin]

I am running V16 RC (Pro license, 8SC) in the Google Cloud on a Linux f1 Micro machine (600 MB RAM). I have had almost continuous problems trying to log into the management console for the past year that I have been using 3CX. While trying to log in as admin, I get a red Server Error message. Restarting the Google Cloud instance fixes the problem.

Sometimes the entire PBX stops working. Restarting the Google Cloud instance fixes the problem.

Recently (since v16), I cannot even surf to the web client login page. The error message is Disconnected. Waiting for network. Restarting the Google Cloud instance fixes the problem.

I am wondering if there are log files I can go through to isolate the problem. It would be easy to just guess that the problem is an underpowered Google Cloud instance, but it is always better to know exactly what the problem is before trying a fix. Perhaps I could just add some swap space.

Any ideas would be appreciated.

Update to this problem: I ssh'ed into the VM and checked /var/log/syslog. This showed some very nasty OOM events (out of memory), followed by the machine restarting itself or continuing somehow. I took this to mean that I should add some swap space, which I have now done (10 GB swap). I hope this may be useful for someone else who is having this problem, and I will update this thread if it fixes the problem.

Hi,

Yes, adding a swap partition will help avoid those issues on smaller machines, let us know how it goes.

Useful info.

You might get away with a swap partition but the Google free f1 micro machines are really underspec'd in the memory department (only 0.6Gb RAM I think).

Personally, I wouldn't let the PBX loose to users without some soak testing to make sure it can handle 8SC.

Update. After two days, the system seems to be running perfectly. No weird problems logging in. I encourage users to make sure there is plenty of swap in their Linux systems. I note that the minimum RAM recommended by 3CX is 2GB, so I do understand @Lee Cramman 's concern.
