Has anyone had a problem with the heat from a drum sander melting the glue joint in tops or backs?

Never had that problem before. How much are you trying to take off at a time? That's what may cause heat build up, or slow feed rate or combination of both. Feed through as fast a possible taking very little off per pass. Also do you have adequate dust collection to the sander. To much dust present will also add to heat build up.

I haven't had the problem yet. I was just curious if there are any glues to avoid.

Glue can gum up the paper if you haven't scraped excess off first. Otherwise follow Rod's advice and you shouldn't have any problems.

Others may do this as well, but after glueing, I always do the first few passes through the drum sander with the top or back set skewed a bit in one direction or the other (i.e. 'not' straight thorough the sander). That way the contact point of the glue joint gets spread out along a couple of inches of paper, which helps keep it from getting clogged up.

There's a point when using titebond 1 where you can scrape excess glue quite easy. It's after about an hour or two when the glue's had a chance to skin over but is still kind of liquid inside the squeeze out. If you catch it at the right time it will almost pop off the wood, not like scraping too soon which will smear or waiting too long and having your scraper skip over the top of it. I always try to catch the sweet spot when I lay up butcher blocks because sending something with that much squeeze out through the a widebelt is a certain way to gum up the belt.

Scrape to throughly remove all glue before sanding. Check carefully to ensure all has been removed.

This right here is an excellent piece of advice. The glue is going to come off and get on the sandpaper (no matter how well you scrape it). Skewing the wood makes sure you don't create a glue line on the drum (DAMHIK).
