At one location, I deal with 4 GDC SX-2000A servers and a GDC TMS. Occasionally, I find I cannot ingest a movie into the TMS and distribute it to the 4 servers, without getting "exception" messages. Doing a file verification gives me a 'hash mismatch' error on both the TMS and servers.
This happens only very infrequently, and usually with DCP's from independent producers or distributors. But last night I found I cannot ingest "American Ultra" into the TMS or distribute it to the auditoriums without getting 'hash mismatch' exception errors.
(all ingestion is being done through the CRU drive bay)
So, this means that I will actually have to GO down to the theater at some point later today and manually ingest "Ultra" into each server locally. Ingesting locally into each auditorium's server always solves the problem.
As I said, this happens very infrequently, but whenever it does, it a big P-I-T-A. I will either have to go down to the theater late tonight after the last show, or go in around 4am 2moro morning to take care of this since I have other commitments I need to work around and GDC's are friggin' slower than molassas in January when attempting to mulitask ingest and playback at the same time. So my best bet is to go do it when nothing else is running at the theater, even though it's a complete drag on my time.
So, any ideas why this occasionally happens?
GDC Serverthingys are SX-2001A's, and as far as I know are up-to-date, software-wise. The TMS was updated to latest version either late last year or early Y2k15.
But this has always happened unpredictably since the system was installed, and always when I have the least time to deal with it.
(I'm sure GDC designed it that way)

Hi Mark- Thanks (as always) for your comments. But, whenever I've had this problem: 1) All the outlying servers HAVE been logged in. 2) Clearing and error & re-trying gives the same "exception" results. 3) As I said in my original post, this happens very infrequently, and in the past, I've only had the problems with drives mastered by smaller 'independent' distributors, and was more prone to happen with material ingested from mini USB drives. This was the first time I've had it happen with a CRU drive from a major distributor.
I suspect that it has something to do with the network wiring, since not only is it a very long run to two of the auditoriums, but I've never been impressed with the quality of the net wiring work the installers did.
In fact on several occasions when I've had this problem, it has only occurred at the two "distant" auditoriums. But last week I couldn't get a clean transfer to even two "local" servers, one of which is located probably less than 20 cable-feet from the TMS.
Here's a question for you: Do have any idea of what the 'average' transfer speed between the TMS and servers is? (or is supposed to be?)
When nothing else is running, the process doesn't seem to take too long, but if you are transferring while playing a show, the network slows down to about the same speed as a turtle on tranquilizers. (or a somewhat somnambulant snail on sleeping salts )
I know ALL systems will do this to some extent when multitasking, but the difference on this one seems extreme. Or is it just the nature of the GDCs?
