The release note may mention curl and may mention dynamic ports exhaustion. In any case, I would post in the threads where the issue was seen that a fix is out - in your case I would a reply here Transcoding errors starting 2-3 days ago - #17 by sa2000
There is a forum preview release - not a beta release
It is available in this forum topic New Plex Media Server movie scanner and agent preview
It is a new scanner for movies libraries. I expect it to get round the problem because the scanning is done in-line by the Plex Media Server process and not a separate scanner process.
So we have music already covered by the new in-line scanner. This forum preview release covers movies. Photos were done much before. So this leaves TV Shows as potential issue
