I'll keep this in they back of my mind as I tromp around in the dump code. I have another solution that may work for you and that is to use Netdump rather than swapdump. This basically eliminates the trip to swap space and you end up going to savecore style output on the netdump server. =20 --=20 Rod Grimes rgrimes@free= bsd.org =20 What does it take for NetDump to work to a FreeNAS (9.10 nightly) server si= nce that=E2=80=99s what is =E2=80=9Cnext to=E2=80=9D this server? =20
