Broken Publishing Server

I have a publishing server that is throwing an error when I try to 'show all' errors in the error log.  I can not delete any errors for this particular server because the buttons do not display.  The error is below. 

The publishing is still working to the web server that this publishing server is dedicated to.  I have restarted the service and both my app server and web server but no change.

Can anyone tell me what may have gone wrong and how to fix this?
