[CentOS] Maybe OT: Mailman keeps breaking.

I have a CenOS vps on which I installed Mailman to handle mailing lists 
for my organization. I was first told about Mailman on this list. The 
problem is that Mailman keeps breaking. Right now, when I try to access 
the web interface I get an internal server error. Fixing it is running 
up fees from my consultant. Unless it can be made stable I will have to 
abandon it.

Thanks,
John
