There are several possibilities: 1. You are nuts, and this is just bad. 2. You are nuts, and this is not bad. 3. You are not nuts, and this is just bad. 4. You are not nuts, but this is not bad. The problem is, we don't have enough information to answer your question. We cannot accurately determine whether you're nuts, or whether this is bad. There's nothing inherently inappropriate about storing arrays in session scope, or submitted form fields, etc. It depends (as Jochem pointed out) on what your application is intended to do, and the potential use-case scenarios around your application. While memory is limited, it's much more efficient to store things in memory rather than refetch them from a database - database interactivity is typically the most expensive portion of an application. If you had unlimited memory at your disposal, it would make perfect sense to just store everything in there until you absolutely have to write it to a persistent data store. But you don't have unlimited memory, so you have a balancing act. We all would need far more information than you've provided to tell you whether you're off-balance one way or the other. I will say this, though - there's a reason we have 64-bit servers nowadays.
