[horde] PostgreSQL connection limit problem

[Daniel A. Ramaley]

Hello. I am running a Horde server with these applications:
  Horde 3.1, Imp 4.1, Ingo 1.1, Passwd 3.0, Turba 2.1
The server is running Red Hat Enterprise AS 4 and using a PostgreSQL 
7.4.8 database.

There appears to be an issue with the PostgreSQL database. So far my 
searches for info have been unhelpful. The first symptom is that the 
message below appears frequently in the PostgreSQL log:

Mar 13 18:06:32 sun12 postgres[20625]: [1-1] LOG:  unexpected EOF on 
client connection

I don't know if that is actually a problem; normally it doesn't seem to 
do anything bad beyond making the logs larger. More serious, however, 
was an incident last week. The database was inaccessible with messages 
like this in the log:

Mar 13 19:31:36 sun12 postgres[20954]: [1-1] FATAL:  connection limit 
exceeded for non-superusers

Needless to say, without the database Horde does not work. Restarting 
PostgreSQL got Horde working again, but i need to make sure this is not 
a common occurrence as. Before i spend too much time on this, has 
anyone else seen a similar problem? Is there a fix for it? Thank you in 
advance for any advice.
