No. Hard to know what the devs are up to here (what stack they're
using, etc), but I'm suggesting one transaction is getting started and
not closed. Warnings have been know to be ignored. I admit I am not
familiar with Kumar's term of "sub-transaction" and how those might be
created but it sounds to me like a transaction is begun early in the
processing and more work happens unaware of the transaction. And
possible not committed.
