( u r attacking yr own site? lolz )

Dhrup, how am I attacking my own site? Any suggestions on how to proceed?

If your log contains entries older than a week though the garbage collector interval is set to 1 week then I would guess your weekly cronjob is not running, i.e. the garbagecollector and logrotate processes are not triggered. What happens if you call these jobs manually, i.e. entering http://yoursite.url/weekly in your browser? Do the older entries remain in the log?

What are the 1 second log entries? What information does the log contain about them? Maybe they are caused by a plugin installed on your site that triggers some high-frequent request?

Thanks for the ideas Dhrup.  I appreciate the help.

well ;-) u said ' The user in each entry is me ( administrator ). ' !?
and, but.. did that phpmyadmin 'empty' empty the log quickly enuff ?!
that's your triage @now, the practicals - can be figured & fixed @later..
(1 per sec *is highhh! wot r u doinggg ? )
do you also have many log_123456789 named log tables ?
delete all those ;-)

I took the site offline, brought it back online and emptied the log table.  The problem seems to have gone away.  Very strange indeed.
