slapdd running at 100% of the cpu?

Slapd was fine this weekend, then yesterday it went to 100% of the CPU and load average of 1.0+. No filesystems are full and I can find no mention of an issue in /var/log/*. Where can I look next for what's going on?

I had this happen a few weeks ago, but I thought it was due to a full file system at the same time.
