We only found a couple of places in the Zebra configuration. One is for disk space for register and shadow files (default is 4GB) and the other deals with maximum memory which I bumped up.
My rationale for the MySQL memory adjustments is in rebuilding the Zebra indexes Zebra indexes the data is being pulled from MySQL and when trying to rebuild the indexes with over 10,000 bibs we started seeing the memory errors. It was worth a shot. Also, I did find a few references on the Koha Wiki and in a few other places that use isam databases (Zebra) about memory allocation and MySQL. I would still like to see a healthy discussion about what the best practices are for allocating memory for Zebra and MySQL. Also, somewhat related to this, the zebraqueue table in MySQL. It seems to continue to build up with every load. Is this normal? Should the zebraqueue table in MySQL be cleared from time to time?
