Re: BUG #18599: server closed the connection unexpectedly

This is a VM based on IBM hardware.
I can dig into the HW side if needed.
I will check on jit setting and see if the issue can be resolved.
As for the stack trace, there is no coredump and the search i did, look ile the pg_backtrace may be the way to go. I have downloaded the sourxe code from GitHub but looking for the make command options for rhel8.9 and any dependencies.
