Thanks guys. I need to figure out which option I should use. Too many
alternatives! :)

OTOH, I never thought we'd need so many hacks to do something like a
planned reboot. I had expected to find a torque / maui inbuilt option.
Is it so uncommon to request reboot on a compute-node?

That would be the neater approach, agreed. I take a pragmatic
approach. 5 minutes lost to reboot every 2 weeks is way cheaper than a
week of digging into badly documented user code to figure out a
zombie, memory leak etc.
