EBPF_READER[1404]: segfault at 10 ip 00000000009deeb5 sp 00007f6939bfc898 error 4 in ebpf.plugin[401000+5f3000] likely on CPU 1 (core 0, socket 0)

It looks like, netdata is causing this.

Server was running for about 40 hours, and the the alert came, that the server isn't reachable.

I also run a cronjob on the server which shows me the ram usage:

@hourly free -m | mail -s "Test" ******************@gmail.com

This was the last mail

              total        used        free      shared  buff/cache   available
Mem:            3880        2826         330          10         971        1054
Swap:              0           0           0

So it looks, like there is enough ram.

I tried to use roundcube from another IP, it was also not reachable. Even the server isn't pingable.

so, roundcube stops working, iredadmin stops working, and you cannot SSH into it

did you try to use roundcube / SSH from another IP when this happens?

also check the fail2ban logfile if your IP gets listed there

Is clamav-daemon service running?

Hello,

I installed iRedMail an Saturday and everything works fine. I can send and receive mails. But after a few hours the server is not responding. Roundcube and iRedAdmin are not reachable. I also cannot log in via ssh on my server. After a restart everything works just fine for like 18 hours.

I have a VPS server so I can't login physically on the machine.
