Our Nimbus server finally crashed due to OOM errors. It's been up for about a week, although we've never encountered this issue before. Any ideas how this can happen? We currently have Nimbus and UI running on a dedicated box with no other apps running. I assume all Nimbus does is monitor supervisors.

We detected this error when the UI responded with stack traces indicating that it could not contact Nimbus.

Sorry, please ignore. Turned out to be an error on our part. Accidental ssh to the Nimbus control port.

You probably want to raise these:
ui.childopts: "-Xmx768m"
nimbus.childopts: "-Xmx1024m"
