FPMSummer on "[Plugin: Blubrry PowerPress Podcasting plugin] Powerpress and MySQL error revisited"

I will clarify why I think the problem is in powerpress, specifically that SQL query.

Powerpress didn't generate this error in earlier versions, I don't have an exact timeline, but I believe it first showed up on my sites with version 3.0.1 or 4.0

The error is EXACTLY the same every time. That one same query, 1000% of the time. Just that one. If it were a true issue with the mysql installation on the server, it would show up with other queries as well, not only just that single one every time, for possibly as long as two years now.

If I had seen other plugins with sql queries causing this error, then I would have started talking with the ISP or the owner of my dedicated servers long ago about digging into the mysql server and perhaps tuning it better. But nothing else on my servers or my sites is throwing this "mysql server has gone away" error. Not one single other plugin or WP installation. Not one that isn't running powerpress.

Millions of queries a week across 3 different servers at two different hosts where my sites are installed, and the only time there's a "mysql server has gone away" error is with the exact same query from the exact same plugin, only, every time?

I've been casually looking into this problem on and off for over a year, and everything points back to an issue in powerpress, simply because it's only that one single query that's generating this error, and none of the other sites on the same server that are not running powerpress ever throw this mysql error. Not ever. Not even other queries from powerpress generate this error.

Given that information, how can you unequivocally state that the problem is not in powerpress? Doesn't it stand to reason that there's something in that query that's incorrect or somehow failing, and the mysql server times out because it cannot return a value? I don't know SQL well enough to dig into why that query pops up and dies without getting a result, but the fact that it's only that one query every single time indicates to me that there's something faulty with that SQL query construction.
