I am getting a PhusionPassenger::Railz::ApplicationSpawner::Error with a Rails application. Even though I did find inside the FAQ that this is most likely a result of an out of memory situation, i am surprised since my free command tells me this:
total used free shared buffers cached
Mem: 16442904 15227688 1215216 0 1970824 9013708
-/+ buffers/cache: 4243156 12199748
Swap: 8000328 573596 7426732
Seems that there is still enough memory to run with all the processes on.
Is there anything to fix this?
