I'm using the latest version of the proxy software, and the latest poclbm.  Since updating to the more verbose poclbm (week or two ago) I see this error all the time:

proxy.hostname.net:80 Problems communicating with bitcoin RPC 0 2

Then it recovers from 0mhash/s and looks like this

proxy.hostname.net:80 93870 khash/sunicating with bitcoin RPC 0 2

until it gets back up to the normal speed (which takes just a second or so).

I see this happen every few seconds give or take.  Has anyone else seen issues like this?  Since the last week or so I've had to stop using this awesome software as that error slows down my hashing.

Thanks

Edit: I'm running Apache on Debian.  Server is tuned to handle a lot of load, and is nowhere near capacity.  I'm not finding any issues in the error_log files and not sure how I can debug further at this point.
