Thanks for the response. No, I am not exceeding the max limit. I tried a test which would exceed the max connections (which is 100 - set in postgresql.conf). The error at that point is
org.postgresql.util.PSQLException: FATAL: sorry, too many clients already

Hi
I am managing an application that uses the Postgres backend. Of late we have started getting connection refused errors every now and then. We have not been able to identify the cause of this. Any hints or known bugs that I should be aware of? Thanks for any help extended!

Here is the environment I work in:
Application is a Java app residing on a web server and is running on Tomcat.
Versions:
jdk: 1.5.0_02
Tomcat 5.5.23
Web server: httpd-2.0.52-28.ent.centos4
Kernel: Linux version 2.6.9-42.0.10.ELsmp (mockbuild@builder5.centos.org ) (gcc version 3.4.6 20060404 (Red Hat 3.4.6-3)) #1 SMP Tue Feb 27 09:40:21 EST 2007
Postgres: 8.1.8 (64 bit version) - postgresql-libs-8.1.8-1PGDG
postgresql-8.1.8-1PGDG
postgresql-server-8.1.8-1PGDG
postgresql-contrib-8.1.8-1PGDG
We use the JDBC2 driver that comes with Postgres.
The specific error we get is:
CDBConnectionPool.newConnection() : SQLException= org.postgresql.util.PSQLException: Connection refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.
Are you exceeding the maximum allowed connections in PostgreSQL? I would start by checking the PostgreSQL logs. If nothing shows up, it may be a network or application configuration issue.
