Nginx keeps becoming non-responsive?

My current home setup is that I have a raspberry pi3b running pihole
and openvpn, and a minipc running proxmox with a few vms/lxcs. I’ve
not setup anything to be exposed externally, and had mainly set up
nginx (on the proxmox machine) just so that I didn’t necessarily have
to remember the various ip and port combinations to access it, however
it seems like if I don’t use nginx for a while it just becomes
completely non responsive? If I reboot its container after a few
minutes I can use it again, but then some time later everything is
just non responsive (even its landing page).
Does anyone have suggestions for what may be going wrong or an
alternative here? (Can’t just use the dns records on the pihole
because some things need non-standard ports, plus the ui is a bit
cumbersome). Proxmox doesn’t show that the nginx container is using
all of its allocated ram, and there should be some extra ram even if
all the containers are maxing themselves out.

How, inside proxmox, is nginx being run ?

Nginx proxy manager as an LXC. Initially setup by tteck’s scripts.

I'll assume you're using docker inside LXC right ?

I don’t believe so….

Well... "docker ps" will snitch it all.

Nevertheless, are you running out of free space on the container ?

NPM is quite loggy...

'top' doesn’t show any docker entries, just 3 nginx entries.

Proxmox says there’s about 1.5gb of the allocated 4gb available,
though it is currently working, so can’t rule out that a restart I did
yesterday cleared some logs out.

When the LXC "crashes", can you check the host logs ? Or maybe dmesg ?
Might it be OOM ?

“Crashes” meaning goes unresponsive? I didn’t see any host logs
anywhere and proxmox didn’t report it as being oom on the dashboard,
and I’m pretty certain I haven’t allocated all of the machines ram.
