Update, Interestingly, i took the value to the wire, setting 'emptyPagesPoolSize' to 510 (< 512) and that seems to have done the trick. Atleast in my past 5 test run's the preload has gone through fine.
Right now i have set it to pretty much the max value, since there is no good way to identify what would be the runtime max value of an instance while creating a cache. Any other ideas around how to go about setting a safe value for this property. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
