random black buckets in corona caustics animation

[garciabores@gmail.com]

Hi there.
I'm rendering an animation with caustics. When i render one frame locally everything looks fine. When I render animation in our render farm (each node renders one frame) random black buckets appear in each frame.
We have all the software and plugins in each node well setup, any other animation without caustics works well, it just fails when we activate the caustics.
Any light on these issue?.
Find attached the frames
Thanks in advance

That's a known issue. To fix it, enable development / experimental stuff options (https://coronarenderer.freshdesk.com/support/solutions/articles/12000021288), then go to advanced caustics solver options, and disable "caustics adaptivity" there.
