Strange HTTP 414 request captured by IDS

My ids is generating so many HTTP 414 requests i.r content Uri is too large, the interesting part is, all these requests are sending from my server to and external IP. I look into Apache and error logs , I couldn't find anything related to 414 status code. even my ids doesn't give much info other than the fallowing info
