I/O operation on closed file

[Saeven]

Hello.

Using supervisor 3.3.3 on OS X, installed through brew.

The system seems to work 'ok'; but the error file is a torrent of errors such as these (below). Any hints appreciated.

Same question with you.Worker status show Running. But supervisor.log show error.

Maybe check your log files to ensure that permissions are adequate for writing. I've run into this before with a similar error message.

Both look the same and are from Supervisor 3.3.3, although it likely occurs in earlier versions as well.
