System Information
Operating system: Linux-5.11.0-7612-generic-x86_64-with-glibc2.32 64 Bits
Graphics card: Radeon RX 580 Series (POLARIS10, DRM 3.40.0, 5.11.0-7612-generic, LLVM 11.0.0) AMD 4.6 (Core Profile) Mesa 21.0.0

Blender Version
Broken: version: 2.93.0 Alpha, branch: master, commit date: 2021-04-13 07:49, hash: 30ee57be60
Worked: 2.92 same scene works with "Persistent Images" ( not performance improvements )

Short description of error
With Persistent Data enabled the "initializing" render of the second frame last forever ( errors from terminal attached. )
PS: Randomly it worked few times ( i do not know why ) with great performance improvement for the frames after the first !

Exact steps for others to reproduce the error
I tried to render few frames in Cycles ( from 2467 to 2470 ) with the new Persistent Data enabled in 2.93.0 Alpha of the Gooseberry scene ( Cosmos Laundromat Demo )
Randomly it worked with 2.93.0 Alpha, but not most of the times.
The same animation scene works with 2.92 with "Persistent Images" enabled ( not he new "Persistent Data" ).

Since the related task has been fixed, could you retry on a build that's newer than https://developer.blender.org/rBcedd8b8c56b944ffdabadc4339d2d1e5c6651dd6 ?

Hello,

i tried the latest experimental builds:

2.93.0 Beta, branch: master, commit date: 2021-04-20 15:45, hash: 3735986e87, type: Release
build date: 2021-04-20, 22:56:03
platform: Linux
3.0.0 Alpha, branch: master, commit date: 2021-04-20 20:43, hash: c5cabb6eb7, type: Release
build date: 2021-04-20, 23:03:52
platform: Linux

and i cannot finish the animation render as it is blocked during the "initializing" of the second frame ( terminal errors attached ).
So in my test the problem is not solved.

Anyway thank you for following the bug :)

Could you create an simpler Blend file to demonstrate the issue ?
Also, see if Blender is running out of memory, or the process is just slow due to swap https://en.wikipedia.org/wiki/Memory_paging#Unix_and_Unix-like_systems.

I tested the Cosmos Laundromat Demo ( Gooseberry scene ).
You can download it here:

https://www.blender.org/download/demo-files/

For now i cannot "demonstrate" the issue, i just reported the bug in this scene with the terminal errors.
If i have the possibility to understand the cause of the issue i would report it ( from the terminal it appears related to bone drivers ).

About the memory i have 32 GB Ram and i checked that Blender is not running out of memory or swap.
I attach a screenshot of the system monitor taken during the "inizializing" process that last forever where i have enough memory and with one cpu at 100% ( i already attached the terminal errors ).

I'm unable to reproduce the problem in latest 2.93. There have been many persistent data fixes since this report, so potentially it was solved by one of them.

Note:
Just come up with this issue again (3.3. Alpha). It's not present when Using CPU (AMD TR 1950X).
It is caused by remnants of BlendLuxCore engine (known there as issue #59 )

To solve it, simply Purge Orphan data (clean scene file of all remnants of LuxCore, even those marked as "Fake Users")
