1024 limit?

Hi,
Im building a server that uses libpq to connect to a database and
authenticate the users that connect.
I do PQfinish for the conn and PQclear for the result so there cant be
a memory leak there.
If I remove the function where I authenticate my server can handle as
much clients as I want.
If I authenticate every clients with connections to the database it
crashes on PQconnectdb at th 1024th client without returning an error(it just
segfaults).
My ulimit -n is more than 1024 btw.

Did anybody encounter such problem?? I've been trying to fix this one
for a long time...

Thanks
-Mat
