Having another volunteer also means more work for us, as we need to communicate with this person regularly. It also means that we maintainers get more removed from the users, and wont be able to talk with them directly anymore. And in my experience, volunteers are very motivated in the beginning, but most of them get bored or busy after a while and then you need to find someone new again. Not really worth the hassle in this case.
Also the database issues mentioned in this thread may simply be from lack of ram.
