Hi,

I get every morning a mail with this error.

Code: Select all

exim paniclog /var/log/exim4/paniclog on **MY HOSTNAME** has non-zero size, mail system might be broken. The last 10 lines are quoted below.

2021-10-13 21:52:42 daemon: accept process fork failed: Cannot allocate memory
2021-10-15 02:50:02 1mbBQA-0003aa-1q 1mbBQA-0003aa-1q bad addresses found in headers
But i have enough free memory.

This also only in my paniclog file:

Anyone knows how to fix this?

Thank you in advance.

Is this "normal"?

Okay, I took a closer look. I can remember once when I wanted to run something on the server, but there was no memory available. So I think that was on 13-10. That explains that error message. That leaves this message:

Code: Select all

2021-10-15 02:50:02 1mbBQA-0003aa-1q 1mbBQA-0003aa-1q bad addresses found in headers
I have not been able to find a clear explanation on the internet. I just then went to see what mail was sent at 02:50. That was this email:

It is true that there was no connection for a while at that time. I did a sudo apt update & upgrade. Then mysql dropped out for a while. I have vesta on two servers, and had also updated another server. That one also had the same error. I think it has already been explained in this one. I have therefore emptied paniclog now.

Is there perhaps something else that needs to be adjusted in VestaCP to avoid this error message? Otherwise, are the error messages in mainlog normal? I don't have all these error messages on another server (with myVesta). There I only have erros like this:

If your exim is up, there is nothing to worry about.
You can see what was the problem by looking that log:

Code: Select all

cat /var/log/exim4/paniclog
Then you can erase panic log with:

Code: Select all

truncate -s 0 /var/log/exim4/paniclog
