JobTempAlloc error appears in Standalone Build output log if trees are in the Scene



Reproduction Steps:
1. Import attached project.
2. Open Test scene.
3. Build and Run.
4. In Standalone Build Data files, open output.log.

Expected result: Allocator errors should not be shown.
Actual result: The following error appears:
"Internal: JobTempAlloc has allocations that are more than 4 frames old - this is not allowed and likely a leak"

Note #1: If trees are removed from terrain, the error no longer appears.
Note #2: No obvious memory leak is detected.

Reproducible with: 5.5.3f1, 5.6.0f3, 2017.1.0p2

    Hey everyone, if shadows is causing this error message again, make a new bug report with that in the title, this one is only regarding the terrain trees. I doubt anyone from Unity is still checking the comments here seeing as it's marked as fixed already. With a new bug report, they will be taking a look at it.

    On 2019.1.14 - same as LEE_UNITY808. Issue is caused if shadows enabled on the directional light. Disabling it stop this error.

    For this is happening when I play Timelines (Playable Director) and seems to hurt the performance.

    Is there a new open ticket for this issue? I can't vote on this issue because it's marked as closed.

    Not fixed in Unity 2019.1.5 + AR Foundation 2.1, soft Shadows enabled.
