System information

A User (gautam.jha):
I’m running Erigon on my Kubernetes cluster for an Ethereum Sepolia node. The setup had been stable for about a month while running erigontech/erigon:v3.0.3 with a memory limit of 45GB.

Starting today (24/02/2026), the pod began getting OOMKilled repeatedly. Due to the frequent restarts, I increased the memory limit to 75GB, but memory consumption continued to rise and is now reaching approximately 130GB RAM.

After the repeated restarts, I upgraded the image from erigontech/erigon:v3.0.3 to erigontech/erigon:v3.3.8 (latest), but the high memory usage persists.

I’m trying to understand:

Why would memory usage suddenly spike after being stable for a month?,
Could this be related to the version upgrade from 3.0.3 to 3.3.8?,
Is there any known memory regression or behavior change in recent releases?,
Could any of my runtime flags be contributing to this?,

Below are the arguments I’m using:

Expected behaviour

Actual behaviour

Starting today, the pod began getting OOMKilled repeatedly. Due to the frequent restarts, I increased the memory limit to 75GB, but memory consumption continued to rise and is now reaching approximately 130GB RAM.

If anyone has seen similar behavior or has suggestions on what to check (cache configuration, snapshot stages, torrent rate, trace/debug API impact, etc.), I’d really appreciate your guidance.

Thanks in advance 🙏
