Did you solve this? We're having a very similar problem, only that it outputs some frames sometimes, but only a fraction of the frames it's supposed to render. Like you, we get no error message. I read somewhere that AE might write useful output to the system.log instead of console, but that didn't happen in our case.
Without any more info on the specifics of the system and the projects that don't render, this is going nowhere...
I am having the same issue as danieln77. Render farm specs: Windows 7 render nodes, Adobe CS5.5.
A look at the logs shows the failed frames hang up aerender at the point it is calling on the program but never gets beyond that... and then it indicates that the frame had been successfully rendered even though nothing was output.
Log for successful frame:

aerender version 10.5x253
As you can see for the failed frame, it doesn't look like any actual rendering is being done, even though the aerender exits with no errors. Any info would be greatly appreciated!

Typically if a node is running more than one instance of aerender, only one of those renders will spit out a completed frame. There have been instances where all instances spit out a frame, or none.. does not seem to be a reason. All the nodes are identical hardware. The project render fines via both the AE interface and command line on each node.
For those of you that are having the same problem, we've reserved all cores on a given node (we have 12 on each node) to render 1 frame. This has fixed the "skipped frames" issue for us.
The question is, is aerender actually utilizing all 12 cores to render the frame? Or is it only using one core even though out distributed rendering system is reserving all 12 cores for that one job?
Edit: Found the answer to the above question... We are using all 12 cores of a node to render 1 frame.
