The problem with Barro is still with us.

Barro and Heckman (the other case) are large

I suspect there is some size limitation that we are hitting.

I don't think there is any limitation built in into ACIS, but I read http://www.mysql.com/news-and-events/newsletter/2003-09/a0000000237.html The theoretical limit in MySQL 4.0 is 2G, however each blob requires generally to have 3 copies of it in the memory (stored in various buffers) so you need a lot of memory, if you have large BLOBs stored in MySQL. This is the reason, why the theoretical limit can be reached only on 64bit systems. The Practical limits are around some hundreds of megs per BLOB. We need more memory, or we can just ignore this issue as the blobs are not actually used?
