Server memory overflow crash

FiveM Server Development Server Discussion

Hello

We have a big problem with our server. In random times the luv_tcp9 and the fivem process (linux) starting to eat our memory (129 GB) and on 100% memory the server chrases. We tried to kick all players when the memory overflow starts, but no changes. We started to search for a buggy script, but when this problem started we dont updated nothing on the server in 20 days.

What/Who can cause this problem?

OS: Debian 11
Build: 5940 (We also tried the recommended version 5848, same error.)

Ps: We tried windows and the server crashed with the same diagnose.

Windows etw stack trace:
2022-10-14_21-25-24_Administrator.etl (55.2 MB)

And a few minutes later it happened again.

2022-10-14_21-41-23_Administrator.etl (59.6 MB)

This sounds like a denial-of-service attack of sorts, without knowing exactly how this is done this might be difficult to fix though.

The .etl files seem to not have been made with the correct settings either (no heap tracing, for example…) and don’t show any significant workload on the TCP threads.
