Since I've installed DSM6 the above error appears frequently (>30%) in the PMS log when PMS is started, and as a consequence PMS stops. This error appears randomly, sometimes during NAS boot, others after manually starting PMS using package manager.
My NAS has an armv5 CPU and 256M RAM. I know it's short, but I've seen other users posting here the same error with Intel platform, therefore I tend to think that this problem is related to some change in DSM6.
Is this issue being acted by Plex Inc ?
