The REGION is set to 512MB within the startup JCL. I didn't know what the
max. is for the region size, so I didn't change that. I will have to look
into increasing that as well. Thanks!

What's your REGION set to on the startup jcl? We're using 768M, but then
we appear to be a smaller implementation than you based on your database
size.
