Don't see any errors but indexing a fairly large set of LXR versions of various programs with genxref program now taking extreme time. Previously only took a few minutes to zip though lots of projects/versions.
See alternating 100% cpu on cores and what looks like constant disk usage and processing now just crawls. Still on 1st project after about an hour (previously took maybe a minute per project).
Top and system monitor don't show extreme processing on mysqld or genxref or any other process (except cores usages rotates and remains 100%).
Recent f16 update included mysqld I think, so my guess is something has change or broken with it.
No errors reported in /var/log/messages or /var/log/mysql.log
