[rt-devel] Handle.pm too many clients

[ivan]

You need to make sure RT won't open more database connections than your
database will accept.

The maximum number of connections opened by the web interface is defined
by MaxClients in your apache config.  The mailgate opens one connection
per delivery.  qmail and Postfix have the option to set a maximum number
of concurrent local deliveries (concurrencylocal for qmail; see
http://www.postfix.org/rate.html#process for postfix).  Sendmail users
have to cripple the entire MTA with MaxDaemonChildren.  Also don't forget
to allow for other uses of the same database backend.
