    It has a red Error icon and reports in the console window:
    Curl error 42: Callback aborted

    It does this at random times and doesn't appear to cause any issues.

    Anyone know what is going on?

    It means something in your project makes web requests and aborts them afterwards.

    What's the reason that makes unity aborts them afterwards.

    My project seems to have this error a lot.

    Why is this an 'error' (like all curl reports) that therefore pauses your editor project if you (as most people would) have 'Error Pause' enabled?
    There is simply no reason for the editor to throw any 'curl' errors.
    And calling a valid function (Abort) on a web call is not a reason to throw an error!!!

    In newer version we filter out curl errors to not show such common types as abort.
    The reason to print them is help investigate web request failures. Investigating why web request fail is very painful and low level error from curl can give a pointer, that's why we started showing them.

    Yes you can show a warning, but not an error IMHO
