I have set up Mailman on a virtual private server from 1and1 running Centos, though I can't tell which version. The system has 2 GB of memory. Mailman is receiving posts, but it is not sending them out to everybody. It is also getting some out-of-memory errors. The server is also runing Plesk for Web hosting. Something on the server is leaking memory. When first booted it has nearly 1.5 GB of free memory. Now this is down to .75 GB. Any hints will be appreciated. Thanks, -- John J.
