PSQL 9.0.1 FATAL: sorry, too many clients already

I have installed PostgreSQL 9.0.1 on my Mac Server (10.6.4) by the .dmg from EnterpriseDB and restored the databases from PSQL 8.4.4.
But now I get an error message in pgAdmin (1.12.1) " FATAL: sorry, too many clients already" and in Servoy 522 Server log:

What is about this? I made two more installations like this on other Mac servers without this error.

Hi Thomas,

What are your connection pool settings on Servoy ?
Also can you check in postgresql.conf what the max_connections is set to ?

Hi Robert,

good questions, but I don’t found anything wrong.
However, I made a complete reinstall of the PSQL 9.0.1 and now it’s working without errors.

Thank you again,
Thomas
