Default Error -20021

We're seeing a lot of errors -20021 in combination with automation too dense messages. After a auto too dense message occurs and you hit play the next time a -20021 (undocumented on the AVID website but according to support plugin related). After -20021 popped up the only way to get PT to play again is to close and re-open the session. I've seen thse a lot a year ago on a complex Atmos mix in combination with a crashing RMU but this is 5.1 and not even yet hit the mixing stage.
Very often this happens after writing AVID Channel-Strip automation. Needless to say that automation isn't dense at all. 99.9% is static EQs across B/Gs or dialogue with ruler-flat automation in edit-session that have not been mixed yet.

We get this on a least 6 different rigs with different session setups and different locations with no apparent thing in common with regards to plugins.

I sent a bunch of log files to support but things went quiet after a while.

Anyone having the same issue?

Thanks

Frank.

Yes I see this too.
It gets worse as the session gets bigger.


I keep thinning automation and that seems to help, but I can't pin down one thing that causes it.


Sometimes I feel its to do with the video engine because I'll get a video engine error followed by a 20021.
Then the timeline will not play and the only fix is a reboot.


Its annoying but it doesn't happen every day.

I just had another couple of these yesterday.
Automation too dense message and then straight to the crash screen.


Nobody else see them, or is it just Frank and I?

Thanks for confirming. I don't see this in connection with video engine issues. In fact I haven't had those in years.
But the pattern is always the same. Auto too dense (which it isn't) followed by the -20021 error and then game over.
Close and re-open session and it's back to normal.
Me and 4-5 other editors on our project get these. Some days with zero issues others with constant errors.

Ditto. What we've found here is this happened on mix sessions created from a template session (not .ptxt, just a simple .ptx) that has been created many years ago (PT10?). 20021 error pops up, then only solution is to restart protools, somedays more, somedays less.

We concur, possibly something related to channelstrip eq automation parameter manipulation. Import session data in a new session didn't work, so we reinstantiated all channel strips on our dialog tracks in the template and it seemed to solve the problem, in one case.

In another instance of that same 20021 error, (different room, different operator, same template) the operator said the problem remains, but didn't manifest as long as he didn't use loop playback. Not sure if he really tried reinstantiating all his eqs (more of the lazy type).

All of this happening on PT12.8.3 Native MacOS 10.12.6. Those systems handle fine all our other projects without issues, most of them heavier than the problematic template.

Hmmm, interesting.
I wonder if it could be template related?
I remember there were problems a few years ago that related to having to re-build templates coming from older versions of PT.
I really don't want to do that half way through a film though, nightmare!


I had 2 days in a row without any of these on the same session, very annoying that its so random.
The last one was after a weird thing were PT was still showing the wrong video track after I'd changed to another one.
Do you guys have multiple video tracks in your sessions?

Default Re: Error -20021

rebuilt templates, imported sessions (data) from older templates into new sessions. New clean o/s installed. Still having the 20021 errors.

Also now it doesn't seem like i'm able to do the inactivate tracks trick to get it working again so having to close and open the session, big pain...

any one got any updates on the issue / found any culprets? Avid are saying it's a dodgy plugin / automation

We had this again during a mix. This time on HDX3, Dolby Atmos setup. Also the usual "random busses stop playing" issue after a track import that I've only known from HDX (actually since HDX was born).

The latter can often be fixed by force-re-shuffling DSP (crtl-option-command-shift-click onto a DSP chip in the system usage window) but not always. Unfortunately it's not related to 20021 as this also happens on a native rig.

hm...

I've just run into this while running an Atmos FX mix session on 2021.7, and the Automation Too Dense warning immediately preceded it. Most of the tracks do have Channel Strip inserts on them.

So was this fixed in a later version?

Ugh, that doesn't sound too good now. Although never really confirmed it does seem like CS is the issue. I haven't used it for a year now and zero 20021 errors.
Unfortunately I might be forced to use it again on the next one (backwards compatibility on a long term episodical).

My support case was never closed and I haven't heard any news from AVID for a year so I assume it's not fixed.
