Error in the event log

Hi all,

Hope you can give me a hand with this error. I can not find information and I don´t really know what is due to. The main thing is that my exchange generates around 200.000 logs per day. I have been having a look at the event log, and I found this error, that comes up every minute:

"(Process w3wp.exe, PID 7972) "Unhandled exception 'Server cannot append header after HTTP headres have been sent

' when processing request /powershell?serializationLevel=Full;ExchClientVer=15.0.712.24;clientApplication=ManagementShell;TargetServer=;PSVersion=3.0&sessionID=Version_15.0_(Build_711.24)=rJqNiZqNgay6ram2u7CtuLLRuLLRu7CytrG2sIHOxsvOxsbJzczNgc7I0M7P0M3PzszfzsbFzMrFys8=."

Any clue to start from???.

Thanks for your replies.
