It has been some time since the first post on this subject on Mar 4, 2009. I had concluded that the issue was a silent failure (i.e., there is no direct feedback) of not enough PHP memory to run Wordpress with several plugins on 1and1. I like running plugins and therefore this situation was unacceptable. I look around for a new host for around the same price $15 a month (I had the developer package at 1and1). I decided on MediaTemple and there (GS) or grid-service package. I found a coupon and am only paying $16 a month. I am much happier with them as they are a first class hoster. If you are in the same situation I would suggest doing the same. This site is currently on MediaTemple and I have lots of plugins running and the site is still snappy. If you do purchase from them please use my referral link: thanks!.
