It survived a couple of -j128 buildworlds with another six -j16 buildworlds running in parallel. But it still has the same issue pho's stress test - a thr1 process is blocked in urdlck. The improvement is that there's only one stuck process and it took 7=BC hrs at INCARNATIONS=3D150 instead of 1-2 hours. (And it runs out of witness locks). --=20 Peter Jeremy --4Ckj6UjgE2iN1+kY Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) iEYEARECAAYFAk5K5aQACgkQ/opHv/APuIfogwCeKFv+2grFALrzUCSnX4SjDoEQ 0QQAn2WTP6oysM7W9KzkPPwjHTV04E6T =PTlB -----END PGP SIGNATURE----- --4Ckj6UjgE2iN1+kY--
