I have an ongoing issue with corrupt Lightroom catalogs. It may be related to large number of images say imports of 2-5,000 images for timelapse, the numbering appears to be random and catalogs corrupt. The import just stops, no error.

Check your drive! This is a very small number of images, I’ve never had such an issue. Make backup to another drive daily!

A backup is to recover from a problem. Yes, I get the back up although I lost two years of work from connecting a RAID to a new IMac but all of those are safety nets. Backups don't solve the problem of corruption.

No a back up will not help you if you backup the corrupted catalog but the point is, you've got some problem with that drive where the catalogs live, IF you're seeing this repeatedly. I've been using LR since before version 1 was released, I've never had a corrupted catalog, not that this is to suggest it's impossible. But it sure sounds like your drive is in bad shape, so I'd look there FIRST. 
Got Time Machine running to back up too?

Yes, time machine is running and this is a new IMac. I understand new drives fail all the time but there does seem to be a correlation with a large import and failure. I have also been using Lightroom from day one. Here is a screen capture of the numbering of files sorted by capture time.

Sorry, I'm not sure what I'm supposed to be seeing in the screen capture. What's this catalog? Can't be corrupted if you can open it so I'm a bit confused.
