Unity 2019.4.2 keeps crashing on build server with Accelerator enabled

    Hi,

    we are upgrading a few projects to Unity 2019.4.2 to move them to the LTS channel. We have Jenkins build server in the office and a Server for Unity Accelerator. We removed the Library / Temp folder to get a clean import after the version upgrade, so Unity has to import everything again.

    This doesn't work with most of the projects. We see in the log that Unity is download metadata from the Accelerator and at some random point Unity is crashing hard and the build fails. We disabled the Accelerator on the build server, now everything works fine.

    We had no problems like this with Unity 2019.3.x.

    Is this a known bug or something we can fix (except from not using Unity 2019.4 or the Accelerator).

    Edit: I already updated the Accelerator from a version from Februrary to the latest one to make sure this is not the issue.

    Thanks
    Tim

    can you cut&paste the callstack from the crash (that should be in your editor.log) to help us determine where the problem might be coming from ?

    No problems so far, this might have fixed it.

    Crash on a different project:

    We updated this project today to Unity 2019.4.4. This is from an iOS build. I triggered a new build which will be started soon. Maybe this was just a random crash.

    Edit: Worked on the second time reimporting the project ...

    @massiveminiteam can you tell me which os you use for Unity Accelerator.
    How to upload assets to server. It seems Assets->Catch Server->Upload All Assets not worked.

    It's a windows server. Accelerator is installed and the Cache Server for older Unity versions is running within a Docker container.
