Description

Eglide weren't responsive for network connections this evening.

It seems the issue is memory related:

/var/log/messages
systemd-udevd[3530]: Failed to fork() worker: Cannot allocate memory
[...]

After a reboot, @jokerozen noticed there isn't any swap configured.

We don't actually have any SWAP configured on this server.

The event triggered the consume of all RAM is probably the @MaxChan eggdrop.

Here the 2020-02-12 14:09 UTC CPU and memory use:

PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM     TIME+ COMMAND

18038 whoami 20 0 1821108 1.6g 844 R 100.0 79.3 123:32.93 eggdrop

Probably a small server only for this eggdrop would be more convenient.
