Memstop: Use LD_PRELOAD to delay process execution when low on memory
There is already memory.high (MemoryHigh= in systems) you can set on cgroups which does something similar at the kernel level.
But its challenging to use correctly. As its easy to end up in a live lock situation where the process never frees memory but also never gets killed.
See all the details that Kubernetes had with introducing this https://github.com/google/cadvisor/pull/3649

OpenTelemetry Profiles Enters Public Alpha
> Like… has anyone done a Jepsen-like stress test on rsyslogd and shared the results? I’ve half-assedly looked before and not been able to find anything.
I've not used rsyslogd specifically, but I don't see how you'd have any issues with the log volume you described.

Solved: Can I run multiple websites on a single dedicated server, and how do I manage them effectively?
Keep a close eye on your server’s CPU, memory, disk I/O, and network usage. Tools like Prometheus with Grafana, or simpler options like htop, Netdata, or cloud provider monitoring, can help identify bottlenecks or misbehaving applications before they impact other sites.
