Hello Thanks for your help.
I know that fixes the problem, but my question was about why I’m getting that error when persistence is on. As far as I know, if persistence is on, off-heap memory holds a subset of data when they don’t fit in memory, and no OOM error should be thrown... unless there are some requirements as the one I pointed out in my previous mail I’m not aware of. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
