cargo test --features big-tests --release test_seal_lifecycle_32gib_porep_id_v1_1_top_8_8_0_api_v1_1 -- --nocapture fails on g6e.16xlarge machine (512GB RAM) which, according to https://github.com/filecoin-project/rust-fil-proofs/blob/master/RELEASE.md#pre-release-testing, should be enough.

The error we're seeing in https://github.com/filecoin-project/rust-fil-proofs/actions/runs/18263575878/job/51994789184 is:

...

error: test failed, to rerun pass `-p filecoin-proofs --test api`

Caused by:
  process didn't exit successfully: `/home/runner/work/rust-fil-proofs/rust-fil-proofs/target/release/deps/api-f61c82f6f1bf5bb2 test_seal_lifecycle_32gib_porep_id_v1_1_top_8_8_0_api_v1_1 --nocapture` (signal: 7, SIGBUS: access to undefined memory)
Error: Process completed with exit code 101.

Here's also a rerun with debug logging enabled - https://github.com/filecoin-project/rust-fil-proofs/actions/runs/18263750505 - which, unfortunately, literally does not provide any additional information.

@vmx Have you seen something similar before by any chance?

@BigLep FYI, this is the current state of the automation setup.
