Autopackager (1.6.3) bug w/ Storage Drawers

[rjenkins2]

Looks like there's a bug with the Autopackager. On my server, I had 1 setup next to a storage drawer (normal, un-upgraded) with gravel, feeding into a storage drawer (normal, un-upgraded) with compressed-gravel. It looks like once the compressed-gravel drawer got full, the autopackager got confused and the game froze. I imagine some kind of infinite loop occurred? The server-watchdog thread would auto-reboot the server because the tick time was > 60 seconds. (It would reboot, only to have the watchdog thread reboot it again because of the bad tick time.) And even after disabling the watchdog, no one could login (of course) because of the problem.

The only way to fix was to remove the Autopackager mod.

This was with the Forever Stranded modpack v1.8.4 / 1.8.5b.

I have not been able to replicate this issue. I tested using a regular chest as the input and a storage drawer as the output. It filled the drawer without issue, and waited, as it should, for space to be available in the drawer. Perhaps it was an issue with the input side?

I was able to replicate this with a modpack with Autopackager, Storage Drawers, Extra Utilities 2 only in it, forge 2239.

It does seem to be related to the input drawer in some way.

I've gotten it to happen a couple times on the following world:

It seems to be related to the autopackager taking out an item at the same time as something else is putting it in?

When it happens the input drawer spams between full (2048) and 2009 super-super fast.

(way faster than the animated gif shows)

I'm not 100% sure what triggers it. The output area needs to be full / filling, and the input area needs to be full / nearly full. It doesn't seem to always happen, probably some kind of race condition between drawers / autopackager? I just played around with taking things in/out of the input drawer / output chest until it (randomly) triggers. I've gotten it to happen twice with the above world.

What's interesting is that the only things that remain interactive are the storage drawers. You can't interact with the nodes / chest. No minecraft commands work, etc... The game is definitely locked up in some kind of loop. You can't quit, you have to manually stop minecraft, etc...
