Memory leak in import job?

[brson]

There's probably a memory leak in the import job. Recently the entire machine came down after the import process was killed, and just now I see it is using 30% of the machine's memory. It should be using just a low constant amount of memory.

I just don't see anything in the code that could leak. There's no caching, no collections, tasks are all joined. Maybe one of the chain clients has a leak.

Probably need to use a heap profiler.

Other jobs use low memory.

I know people have used massif for heap profiling rust.

Import job was taking 50% of ram when I logged in.

Memory usage looks much better after some dependency upgrades.

Memory usage for the import job was at a steady low number, but today I noticed that Arbitrum fell behind, and memory usage is at 27%.

Is there some memory being held by import jobs that run forever? I don't know what it would be.

[brson]

Memory usage immediately rises to 20% again.
