How would you like to monitor "inactive", "cache" and "free" from either "systat -v" or "vmstat -s" whilst the problem is occurring. Does something like perl -e '$x =3D "x" x 10000000;' temporarily correct the problem? --=20 Peter Jeremy --82I3+IH0IqGh5yIs Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (FreeBSD) iEYEARECAAYFAkwQn4YACgkQ/opHv/APuIcB1wCgrdULTyjAmBBdPnx1t0b4XFSj bU8AoLvsCgKcm2xInLijQgSYP/5jt/5W =sJDK -----END PGP SIGNATURE----- --82I3+IH0IqGh5yIs--
