Confuse issue with uvloop

[healfy]

Can some one explain? I try write to file, but i get this traceback, and the main thread freezes and nothing happens. I use:

• Ubuntu 18.04 LTS
• python 3.6.1
• uvloop~=0.14
• aiofile==1.5.2 Traceback (most recent call last): File "aiofile/posix_aio.pyx", line 179, in aiofile.posix_aio.AIOOperation._set_result File "aiofile/posix_aio.pyx", line 180, in aiofile.posix_aio.AIOOperation._set_result File "uvloop/loop.pyx", line 1265, in uvloop.loop.Loop.call_soon_threadsafe File "uvloop/loop.pyx", line 634, in uvloop.loop.Loop._call_soon File "uvloop/cbhandles.pyx", line 341, in uvloop.loop.new_Handle File "uvloop/cbhandles.pyx", line 15, in uvloop.loop.Handle._set_loop File "uvloop/cbhandles.pyx", line 428, in uvloop.loop.extract_stack ValueError: call stack is not deep enough Exception ignored in: 'aiofile.posix_aio.on_event' Traceback (most recent call last): File "aiofile/posix_aio.pyx", line 179, in aiofile.posix_aio.AIOOperation._set_result File "aiofile/posix_aio.pyx", line 180, in aiofile.posix_aio.AIOOperation._set_result File "uvloop/loop.pyx", line 1265, in uvloop.loop.Loop.call_soon_threadsafe File "uvloop/loop.pyx", line 634, in uvloop.loop.Loop._call_soon File "uvloop/cbhandles.pyx", line 341, in uvloop.loop.new_Handle File "uvloop/cbhandles.pyx", line 15, in uvloop.loop.Handle._set_loop File "uvloop/cbhandles.pyx", line 428, in uvloop.loop.extract_stack ValueError: call stack is not deep enough
