Plex server keeps NAS awake

Hi, I have the DL2100 and the EX2100 and installed the Plex Media Server on them (updated to current version). I have noticed that when the server on is but not actively streaming a movie, the system will not go to sleep…Is this normal? Is the server port for Plex always active and there by keeping the DL2100 awake?

Thanks in advance,
tru

If there is a request from your network pinging DLNA servers then it may keep your unit awake.
