And if php.ini settings are reasonable. You also need to be clear about how you measured 1.8 G -- What you are looking at may be a record of how much RAM PHP used at the maximum, for some particularly long/nasty Newsletter with attachments and photos or something... -- Some people have a "gift" link here.
