RP/TUX 6.5, TUX 6.51 - Solaris - GWTDOMAIN dumps a core (Doc ID 773807.1)

Goal

DESCRIPTION:
Timing might cause GWTDOMAIN to dump a core.

CONFIGURATION:
export GW_VALIDATE_HOST=YES
tmboot -A -s DMADM -s GWADM
truss -u \* -u !libc,libc_psr -a -o GWT.out GWTDOMAIN -g 10 -i 31 -u <username> -U /tmp/ULOG -m 0 -A
    or
Obtained the same core letting the configuration up overnight

The customer is reproducing this each time on his low-end platform with fast network. Slowing the network works around this.

Stack trace looks like
program terminated by signal BUS (invalid address alignment)
    or
program terminated by signal SEGV (no mapping at the fault address)
