Hi All

Im receiving the following error, on a php page, conneting to postgres 7.4, installed on Mandrake 10.0
<snip>
Error Description: pg_connect(): Unable to connect to PostgreSQL server: FATAL: sorry, too many clients already . 
</snip>
Can anyone tell me what this means?
Is there a performance setting I need to set under the postgresql conf file.
I have checked, and its set to 100 users.
This error strangely has only happened once. Last week Monday.

Kind Regards,
Shaun Clements
