Can not always connect to postmaster. Sometimes get "Connection refused".

Hi,

We're running postgres7.3 on RedHat7.3. The Postgres at boot time is
started up from a java (1.2) class that runs the following commands in
order:

/usr/local/pgsql/bin/pg_ctl -w start -D /var/lib/pgsql -l
/var/log/pgsqld.log -o -i

/usr/local/pgsql/bin/createdb management

.

.

.

As you can tell the postmaster starts up with "-i" option here.

In pg_hba.conf we have:

local all all
trust

host all all 127.0.0.1 255.255.255.255
trust

host all all 192.168.0.0 255.255.0.0
trust

The host IP address is 192.168.55.5 which is in the right subnet.

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

In postgresql.conf:

#

# Connection Parameters

#

tcpip_socket = true

#ssl = false

max_connections = 64

#superuser_reserved_connections = 2

#port = 5432

#hostname_lookup = false

#show_source_port = false

#unix_socket_directory = ''

#unix_socket_group = ''

#unix_socket_permissions = 0777 # octal

As you can see tcpip_socket = true

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Sometimes, after Postgres starts up, when the database clients try to
access the db from the localhost, we get the following error:

com.solarmetric.kodo.Runtime -
com.solarmetric.kodo.runtime.FatalDataStoreException: Connection
refused. Check that the hostname and port are correct and that the
postmaster is accepting TCP/IP connections.

Any ideas what's causing postmaster NOT to accept connections some of
the time?

This problem almost always goes away upon rebooting the machine.

Any help is much appreciated.

Thanks,

-Allen
