Docker stop to work an have to restart

trondandre

Our mail server has been running perfectly fine for over a year but now it has suddenly started to stop running. There is no logic in when it stops but we see that the error comes from Docker. When we check docker it is running but still we have to restart it and then everything works perfectly again but after a while (sometimes a short while) we have to restart docker again. Memory consumption is only 3% and CPU there is plenty left and this is a powerful server with 384Gb ram and an AMD AMD Ryzen 9 5950X 16-Core Processor, 32 cores and nothing indicates that something from mailcow has eaten up ram or CPU. Has anyone here had the same problem or know how we can fix this?

Well first of all, you have some error log right? How about to post it?

My guess is you have HW problem there,.. can you provide specific model of your MB and RAM? As far as I know AM4 and this CPU support four DDR4 channels usually caped at 128 GB RAM combined, that is 3x less than you have?

The error log do not show any errors.
The hardware can not this problem becuse we have also try out several server we run and when migrate all the domain and mailboxes to another servers the problem also comes up in this servers.

trondandre I don’t think I could solve your issue but maybe list the OS you are using . How you have mailcow installed would help. More details would maybe help.

trondandre There is a almalinux forum you could try to ask on there. Doing some searching shows some issues with Almalinux and docker.
