Warning on elasticsearch logs

(piter) #1

With an old version of elasticsearch ( 1.4.3 ) I have several warning.

Can you explicate me what mean this warning?

It means that you are suffering from heap pressure. I would recommend either increasing the amount of heap available to each node or reduce the amount of heap used, e.g. by deleting data.
