6 months ago Hey @thevops! Thanks for this report!
We investigated that issue and executed some profiling. We detected a goroutine leak in the GetLatestBlockHeight function of our Electrum client implementation (specifically, in the go-electrum's SubscribeHeaders function used under the hood) that is periodically called from within the client info module (metrics and diagnostics):
We opened the following PRs that should fix the problem:
- https://github.com/keep-network/go-electrum/pull/5
- https://github.com/keep-network/keep-core/pull/3775
Once they are merged, this issue will close automatically. Feel free to re-open if the problem persists.
I've noticed that my nodes take more and more memory over time.
Please, take a look at the chart below. It shows 120 days back to now. A memory unit is MiB.
Restarts, including version upgrades, cause spikes (eg. 09/21 = 21 Sep).
