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.
