At which periodicity do you run rebuild_zebra.pl? With such a large
catalog you may run an instance of the script whith a previous one still
running. You could try to run rebuild_zebra less frequently. If your
records are 'clean', you can also run rebuild_zebra with 'nosanitize'
option. It will significantly decrease rebuild_zebra execution time.
