Re: how can I prevent "too many open files"?

Xindice and all XML Databases are really designed to have a few fixed 
number of collections open and lots of individual xml files. I would 
recommend finding another way to use the collections.

If you set on having lots of collections which no matter what probably 
won't scale try using the Embeded database where you could get better 
access to the in memory collections.

Quick question how many collections are you opening?
