mediatemple: mtr start

If you see messages like this

"application started, but pid file was not found, check 'mtr status' "

when doing mtr start/restart, it could be caused by several reasons: first, you need to read RAILS_ROOT/log/*, if it does not help - check your config/environment.rb for initializing RAILS_GEM_VERSION - rails version on (mt) can be different from your dev server.

Next thing to check is whether your gs-container is capable of working with your app. When you try to run several apps on default free 64M Container (and that was my case), the earliest process will be killed and you'll get no messages but this default 'pid was not found'.
