[Zope] My Data.fs won't pack with 2.1.3

I'm using Zope 2.1.3 When I try to pack my database (about 300M) I get a browser timeout. The python process seems to keep packing for a while after that. When all is done the database is the same size (the first time it was .1M bigger) and there is a Data.fs.pack file left in the var directory. The Data.fs should pack down quite a bit because I previously deleted a large portion of the stuff in the database. Has anyone seen this and does anyone know how to fix it?
