Release Notes 330.4 (July 2026)

Some sites found that a Pro2 CDC queue would refuse to come back up after the database was restarted — it would start, immediately decide it was "already running" somewhere else, and shut itself down again. The only way back was a manual workaround.

The cause was on ProTop's side. To show you whether a queue is Running or Down, ProTop briefly checks a status row that Pro2 also uses to track its own startup. On a stopped queue, ProTop was hanging on to that row a moment too long between checks. When Pro2 then tried to start, it saw the row still held, assumed another copy was already active, and stopped.

330.4 fixes this: ProTop now fully lets go of the row after every check. The Running/Down check itself is unchanged, so monitoring works exactly as before — and stopped queues start cleanly again. We've also added an automated test that reproduces the original failure, so this can't quietly return.
