[horde] Memory Exhaustion Problems

[Kevin M. Myer]

As a simple enhancement to your existing setup, try running MySQL on a 
separate
server - one server (or cluster) for web, one server (or cluster) for 
mail, one
server (or cluster) for database.

Pare down your Apache and PHP modules as much as possible.

You don't mention the number of users but one Gb of RAM is not a lot, 
especially
if you are running Apache and MySQL on the same server and have any volume of
users.

What kernel version are you running?
