--BXVAT5kNtrzKuDFl Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Looking at the sources: The 'blocked' column in vmstat is the sum of (struct vmtotal).t_dw /* jobs in ``disk wait'' (neg priority) */ and (struct vmtotal).t_pw /* jobs in page wait */ 'systat -v' splits these into two fields (Proc:d and Proc:p) as does sysctl vm.vmtotal It's difficult to map these counters onto ps output. State 'D' and 'W' should catch most of them. You might find it useful looking through the MWCHAN column for anything looking suspicious. --=20 Peter Jeremy --BXVAT5kNtrzKuDFl Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (FreeBSD) iD8DBQFEoOIr/opHv/APuIcRAlkxAJ0e1dVZU3iCrlKU6kS5L0tfHyYr/ACgjwUX fgpsw8qTHfjpF31uRYlo94o= =SROZ -----END PGP SIGNATURE----- --BXVAT5kNtrzKuDFl--
