Great that you caught the trace. Very interesting, the trace suggests there's a lock contention in the tx_pool. Thanks!

This was a bit unfortunate timing. The bug which (apparently) caused this lockup was already present on master for the entire week last week while you were running the memory tests. I've pushed a fix onto master, will release a hotfix shortly. I really hope this (#16843) was the issue.

Thanks for the quick turnaround with this
