Thanks for sharing this info. Will remember for future debugging too. Checked the vm.swappiness and as suggested by Jean-Marc and it is definitely not set to 0. But since we are not swapping I doubt that's the issue here. > > You really don't have a lot of memory, and you have a 5GB heap... MSLABS > on?

I have GC logs on and don't see stop the world GC pauses. GC logs are filling up quickly but I have noticed that on my high RAM instances too.
