Data too large, data for [<transport_request>]

[Dawood (Samra)]

i got the following in elasticsearch container logs:
log:[parent] Data too large, data for [<transport_request>] would be [1020455062/973.1mb], which is larger than the limit of [1011774259/964.9mb], real usage: [1020454800/973.1mb], new bytes reserved: [262/262b]

After a research i find that this is the solution:
modify java options via environment ES_JAVA_OPTS to increase heap size

6:20

increase both values at the same time Xms and Xmx.

I made the change and change it to 2gb instead of 1gb in both. After the change the pods failed to start with the following log:
