I'm trying to script something similar to cascading deletes for a particular site. So the effect of this script is to delete every item from every list in the site that has the metadata of my choice. This actually seems to work and does delete the items within the lists that have the column and data I've chosen. What appears to be the problem is my box comes to a crashing halt shortly thereafter, so I'm thinking I've wrote into my script a memory leak of some sort. I'm a bit new to powershell and would love to have an expert look over my script and show me what I've done wrong.

Cheers,
Matt B.
