Piperack has a memory problem

[PieterLamers]

Hi Norm, I'm using piperack to start a short pipeline generating an ONIX file as output. When I call the pipeline a few hundred times, memory consumption grows over 5GB and is not returned. This means that there will be a Java heap space error if I make enough calls. The moment at which the heap space error kicks is dependent on the piperack memory, which I've now set to 12GB. I have no idea if I can provide you with any further valuable information, but thought it would be nice to let you know anyhow.
