We are having problems ingesting KDM's to a Dolby DSS-200 server. When we try to send a KDM from the LMS or directly from a USB gives us an error saying "insuficient space..." but the server as a lot of space in the hard drives.

We are able to do transfers of content and SPL's.

What LMS are you using?

Is this a cat862 based DSS200? Or is there an IMB in the projector?

Count the KDMs currently loaded. How many are in there?

What version of software are you using?

Licenses are stored on the media block. There is limited space on the Cat 862 (and, I would assume, the Cat 745 as well) to store KDMs and unused KDMs are not deleted until they expire.

Delete all KDMs from the player (you can't selectively delete them) and re-ingest just the ones you need. Just make sure you have a copy of all needed KDMs before you delete them from the player.

Our KDMs have stopped being deleted automatically on our DSS200.. there are ones from months ago still showing on there as expired. I assume I should delete them all and reingest the current ones to prevent this problem?

I've heard that before but I thought the KDMs would be automatically deleted. What version are you running? Any chance something got broken on some sw version?

The weird thing with this...I've had exactly one site go through the CAT862 being full of KDMs...and it happened to effectively ALL screens at the site. They use a Cinedigm TMS system but I have many sites that have the same configuration but just the one site had the problem and the age of the servers varies from 2009 (Hello Avatar!) on up to the big conversions that started after series 2s came out...I want to say the bulk of the servers were installed in 2011.

They are currently on System 4.7.3.3 (we update about twice per year and based on potential benefits of the new version...they have a DSS100/DSP100 on site and 4.7.3.3 is the last version for that and is DCI compliant...a requirement for VPF plans).

I'm wondering if it was the path that was taken (which updates it had) that "broke" the auto KDM deletion though I didn't count 200 active KDMs in the CAT862 (that is the limit). However, deleting the KDMs did "fix" the problem. So I wonder if it will ever come back. And if the problem didn't start with 4.7.3.3 now that the CAT862s are empty (well, since the deletion about 3 weeks ago) if all is good now. I suspect that all but the DSS100 will be updated to some form of 4.8 or 4.9 by this time next year and there are CAT862 software changes in those.

I have not had it happen in any other site yet and they all are of similar age in terms of the DCinema conversion.

Show manager version 4.7.2.33

Media Block version 4.6.0.12

Screen Server version 4.7.2.1

It is affecting both screens here (we have 2 screens and use one as a TMS)

Just counted and we have 190 KDMs so if there is a 200 limit I better delete them ASAP!

Might I be better waiting until after the holiday period to press delete just in case we run into any problems? Can't imagine many techs being happy having to come out over the Christmas period if we did run into any issues. We shouldn't be getting any more KDMs until the week commencing 2nd January..

If you have the KDMs...you're safe...just make sure you have the KDMs! And yes, it is a 200 limit.

Thanks Steve, will have a go later. We'll have all the KDMs as they're all emailed and I save all the emails. I'll double check before hitting the button though!

The fun is that we've just sorted out the Enigma getting full of logs... now we have the MediaBlock full of KDMs!

We've seen a lot of this lately.

It all started with KDMs for trailers from Warner Bros, which were badly formatted, one had an closing date set before it had actually opened, the replacement had the same UUID as the original (you can easily see why that isn't going to work).

It would appear that the software doesn't deal with stupid human mistakes such as the above, and that the KDM angine or whatever we're calling it 'stalls' for want of a better word.

Deleting all KDMs and ingesting only those you need sorts it.

That'll be what caused it for us then - a dodgy Interstellar KDM. Quite why trailers need KDMs is another thing..

There is another potential bombshell that is starting to crop up...particularly in VPF sites with a Cinedigm TCC...the CAT862 Audit Logs can fill up. With a Cinedigm system, you get a bout 2-years before the CAT862 will reboot itself because the logs are full (interrupting a show). It would appear that the TCC can "flood" the CAT862 with audit requests and each request is logged so it fills them up extra fast.

I know Dolby is working on a "fix" for it in an upcoming release.

If you have the problem, tech support can help with a way to purge the audit logs (to give you another 2-years or so). Purging the audit logs is not always ideal in a VPF plan since those are the logs used for VPFs.

The logs can also be purged by reinstalling the CAT862 software and ticking the "install all components" checkbox. This can't be done remotely, however.

What version of software are you using?

LMS - Cinedigm
Dolby DSS-200 - Internal Media Block (not in projector)
KDM - 12 (currently)
Version - 4.2.1.3 This is the only system that is in this version because the projector is a NEC 1600A. It was working well till the day a made the first post.

We still having the problem.

Here is a pic of the problem.

if you click on the "existing" tab you say you have 12 KDMs?

1st, I would upgrade that software. You have no reasons to stay on 4.2. You should have at least 4.3.5-x, with X currently being 13 but Brad will advise you to stay on 9.
2nd. Try deleting all the KDMs and reloading just the ones you need. Obviously you will have to make sure you have the KDMs you need on a drive before you delete the whole lot.

Does Im going to have compatibility issues/problems with upgrading to version 4.3.5-x with a series 1 NEC 1600C projector?
