OutOfMemory Issues when running chain

[maxp1256]

Hello
I'm trying to run teku (chain) but I'm experiencing OutOfMemory errors. When I set TEKU_OPTS to 10 or -Xmx12G it's working, but there is a very high cpu usage (>90%) at a 4 core Hyper-V-VM on a i7-7740X.

Is this a normal behaviour? Are there any further recommendations?

hey there, thanks for raising this.
Initially can we ask what version of teku, and also what -Xmx you had with OOM, and other command arguments that you may have set when running?
Operating system would also be of interest...

Hello @rolfyone,
I'm using latest teku 24.6.1 (sorry thought that it was the latest one - I'll check again after updating)

I got an OOM with 8G, 10G was stable and 12G also, but CPU usage didn't change.

OS is Win10 22H2 (with latest updates)

Java openjdk 19.0.2 2023-01-17
Zulu19.32+13-CA

Arguments are the default one for chain only (--network=mainnet --eth1-endpoint --rest-api-enabled=true --metrics-enabled --ee-endpoint --p2p-peer-lower-bound=120 --p2p-peer-upper-bound=150)

I've raised cpu cores from 4 to 6 in hyper-v, so CPU usage has lowered to 25-75%

I'm still getting sometimes a "Late Block Import" with arrival 2000-3198 ms and processed 1500ms-3200ms

Hey, my expectation would be that 8G would be fine on mainnet currently as long as there's adequate CPU.
I'd definitely recommend updating beyond 24.6.1, there's been a number of enhancements and security fixes in the last six months. It will be worth looking at the 'breaking changes' since 24.6.1.

@maxp1256 is this still happening ? any more information?

Closing, assuming we're resolved here but feel free to open a new issue if we get more information.
