Francesco Nigro updated ARTEMIS-3021:
-------------------------------------
Description:
This is affecting clustered Core messages.
The process that cause the wrong estimation is:
# add route information to the message
# get memory estimation for paging without accounting the new route information
# getting persist size for durable append on journal or to update queue
statistics trigger a re-encoding
# re-encoding can enlarge the message buffer to be the next power of 2
available capacity
The 2 fixes are:
* getting a correct memory estimation of the message
* save the buffer on encoding to grow using the default Netty
ByteBuf::ensureCapacity grow strategy
> OOM due to wrong CORE clustered message memory estimation
