Same here.
it says “503 Service Unavailable” when i try to access my plex server

If a deadlock arises, then requests will hang and after a while as the number of queued requests reaches a very high level, requests would get rejected with error 503

It is possible that the issue is that which was reported in this forum topic
http://forums.plex.tv/discussion/291861/server-crashes-after-60-min-of-live-stream
A fix will be released for that soon.

If it is a deadlock, it would only be possible to confirm if it is the same issue if server logs and a process dump is obtained - as can be seen in that forum topic
