Warnings: lost track of future

[bje-]

I am seeing these noisy warnings from Scoop 0.7.2.0 like so:

[2023-03-13 19:12:49,554] scoopzmq  (b'127.0.0.1:56766') WARNING Lost track of future (b'127.0.0.1:56766', 645):evaluate([...]],){}=None. Resending it...

Then, briefly, later, I see:

[2023-03-13 19:12:54,308] _types    (b'127.0.0.1:56766') WARNING b'127.0.0.1:56766': Received an unexpected future: (b'127.0.0.1:56766', 645)
