Thanks posde. It didn't make a difference, but I killed the mysqld process and it started behaving after that. If I reboot, it hangs again, but after I kill it, all is well. Mysqld restarts and runs under 20% with a few spikes to 80% or so, but so far it's behaving. Not sure why it spikes after a reboot. This latest version of LMCE just doesn't seem as stable as the previous version about 6 months ago.
