I figured out what my issue was.  I had turned on submitting stales after the post the other day saying it should be okay to enable.  After a few days, one of my rigs went bonkers with the amount of rejects.  I've disabled submitting stales on all three of them now and everything seems to have calmed back down for me.  Going through my log files, it doesn't look like many were accepted anyway, so no great loss for me.  Glad to be back to full strength to join in on today's profits!  Also glad to see the pool growing!
