Customer had this issue a month ago and unfortunately at that
time there was no coredump available and only a hotspot.

The application crashed again and this time we have collected
a dataset which includes a hotspot and coredump (pkgapp output)

The customer is requesting an RCA to be completed

The dataset is located on CORES2
/cores_data/pool-0/data4/3-6908991941

The stack is as follows

They have not been able to reliably reproduce this issue yet
but are continuing attempts to reprocuce.

One of our senior engineers has done some analysis on the corefile / pkgapp
dataset which follows

HTTP requests ends with HTTP/1.1\r\n.

So the key is, reproducing it reliably. And then get a fix so that we know
it is fixed.
