Far as restarts, you being a Java guy on distributed systems might find the Micro-Reboots paper interesting too as it ties into above tip: https://www.usenix.org/legacy/event/osdi04/tech/full_papers/candea/candea.pdf https://www.usenix.org/legacy/event/osdi04/tech/full_papers/... https://radlab.cs.berkeley.edu/people/fox/static/pubs/pdf/j03.pdf https://radlab.cs.berkeley.edu/people/fox/static/pubs/pdf/j0...
