In my experience, the problem isn't so much the savecore time as the time to run /usr/bin/crashinfo. Whilst savecore needs to run early (before anything tramples on the crashdump in swap), the latter could run at any time. It would seem reasonable to either run crashinfo in the background or as a batchjob triggered by /etc/rc.d/savecore.

Maybe the default install should include a minfree set to (say) 512MB. --=20 Peter Jeremy --8w3uRX/HFJGApMzv Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.15 (FreeBSD) iEYEARECAAYFAkydLAAACgkQ/opHv/APuIeBZwCgrPXGmE7tyoHtpXnxO14kZa9q ezAAoIqq9p9cKpm2pD4gHQbBqSEWcATJ =tjph -----END PGP SIGNATURE----- --8w3uRX/HFJGApMzv--
