Hi.

Does this error occur randomly or every time a message is logged?

[aryeko]

@Delgan I have such exception form some point for every logged message until the process killed (due to Bad file descriptor I guess). Attached the exceptions part from my log file loguru exceptions.log

I'm using version 0.5.3 with the following configuration:

from loguru import logger

logger.remove()
logger.add("hub.log",
            colorize=True, 
            format="<green>{time:YYYY-MM-DD HH:mm:ss.SSS}</green> | <level>{level:<8}| {message}</level>", 
            level="DEBUG",
            rotation="50 MB", # Automatically rotate too big file
            enqueue=True) # Process/thread safe logging

Can I protect my app from loguru errors with the API by adding a global exception handler or something similar?

Thanks!

The version I use is' 0.6.0 '. The following error will be prompted after the deployment of Linux docker. How to solve this problem?

I have the same problem in version "0.7.2"

[Delgan]

@middlestone Can you provide more info please, such as how often it occurs and whether a particular action triggers the error?

A fully reproducible example would be of great help. Right now, I can't say if it's a bug within Loguru or not.
