Troubleshooting redirect issue

We noticed that last week all of a sudden our apache access times jumped significantly (quadrupled) from what had basically been a flatline (via monitoring graphs provided by our host). We were looking at these charts because we had in fact been noticing longer load times. We're on the latest mu and buddypress 1.0.3.

Our host said in the last week the error below had been occurring frequently in the last week.... it indicates a redirect error, but looks like the referrer is our CSS stylesheet and an external site, which indicates that it might be a situation where when a bad link is accessed, a 404 is not 404'ing, but redirecting...... something I've read a little about on buddypress.org and mu.wordpress.com where no resolution seems to have been found.

I'm not completely convinced that this redirect is the cause of our increased apache response times as the increased times occur day and night on the charts, where I would expect them to lower at night when the server is accessed less, but this is not the case.

Besides learning how to use SSH (learning later this week), any places we might want to look first in order to troubleshoot?
