There was a problem hiding this comment.
I had to put a wait(delay(0)) above the continue; on line 69, because getMore returns when there's a message, or when the version changes, and it appears we now have a very large number of version changes in a row. When that happens, there's a loop of wait(getMore) -> break -> !hasMessage() -> continue -> wait(getMore) that overflows the stack.
…en different numbers of logs
…of transaction logs because of forced recoveries
…ges of empty versions
… will become after changing the number of txs tags
