Thanks but the core is not very usefull for me because to take an
accurate stack trace, I have to have identical environment as you. Can
you please take a stack trace on the machine where the core dump files
were generated. i.e.
gdb /usr/bin/pgpool core-pgpool-11-0-0-8096-1447690344
> bt (from gdb prompt)
Best regards,
