Hello Milan

Thanx for your reply.

We had a look at the said parameters with the admin and he changed them.

However the problem still persists. Interestingly, the 'Too many files
open' error is limited to firebird. There are numerous virtual hosts
running
in use shared hosting environment and there are numerous file opening and
closing sessions which conclude ok only firebird returns 'Too many files
open'.

For example i created 1000 files on the server wrote 1024 bytes in each and
closed the files. all went very ok
