--NDin8bjvE/0mNLFQ Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable I'm getting the above message when running Peter Holm's stress test with INCARNATIONS=3D150 on a 16-core sparc. Does this mean LOCK_CHILDCOUNT is too low or does it indicate a leak in witness lock_list_entry's somewhere? The comment on LOCK_CHILDCOUNT indicates it is dimensioned to allow 2048 threads to hold 5 locks each but it's not clear how many threads will get started at a given INCARNATIONS count. --=20 Peter Jeremy --NDin8bjvE/0mNLFQ Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) iEYEARECAAYFAk5K6FkACgkQ/opHv/APuIeAQgCglkSVFOJZ3UYkqhMzkrGsHxuC nlkAnj6oatwGl89WsBE5ufv4mL0IWybk =hyHL -----END PGP SIGNATURE----- --NDin8bjvE/0mNLFQ--
