This commit appears to be causing issues with the multimedia/plexmediaserver port. One of the tasks of this software is to do video decoding, and after = this patch that breaks. Sometimes its HTTP-based API fails to respond, and also there are a many connections in LAST_ACK state: $ netstat -4n|grep LAST_ACK|wc -l 415 $ netstat -4n|grep LAST_ACK|grep "127.0.0.1.32400"|wc -l 396 127.0.0.1.32400 corresponds to the Plex API endpoint. Reverting this patch fixes the issue.
