The only time I recall running out of semaphores was when running many (> 
50) Postgres clusters on the same server. And it was easy to fix.

What mode are you running Interchange in? (Is PreFork enabled?)

Are you using any nonstandard Perl modules?

I don't understand how "failed backups" would lead you anywhere with this. 
If you can explain that in more detail I might get a better picture of 
what's going on.
