Okay, it looks like the stack smashing issue has been
resolved through increased allocation of memory in several places on the MySQL
server.
Our server has 8GB of memory with a quad core processor. I
allocated 1000GB to the MyISAM sort buffer size. I also increased the key
buffer size. I found a few things about memory, but not much, on the Koha Wiki.
I would like to hear from others what you have found to be optimal memory
allocation for MySQL with about 20,000 bibs. Also, what would the optimal
memory allocation for Zebra to use for indexing (or reindexing).
Thanks,
John Chadwick
