Hi All, I went through the documentation present at https://apacheignite.readme.io/docs/swap-space <https://apacheignite.readme.io/docs/swap-space> It states that if the maxSize parameter of the data region is more than the size of the RAM, the OS will take care of the swapping. This is to avoid the OOM error. However even after the following configuration, I am getting the OOM error
