Interesting WP Error
 

These are errors I've never seen before, though I should say I have a quirky problem within some posts that could point to this being the problem. Hoping this looks familiar to someone, don't know whether I need to get out my wrench or screwdriver...

(32)Broken pipe: core_output_filter: writing data to the network
(57)Socket is not connected: core_output_filter: writing data to the network

Any help would be much appreciated
