Django+uWSGI高并发场景下出现BlockingIOError问题求助

应用接收到大量请求时，出现以下错误：

BlockingIOError: [Errno 11] write could not complete without blocking


 print(ServDHCPRelay,"ServDHCPRelay")
  File "/apps/netadc3/.venvs3/netadc3.8/lib64/python3.8/site-packages/colorama/ansitowin32.py", line 41, in write
    self.__convertor.write(text)
  File "/apps/netadc3/.venvs3/netadc3.8/lib64/python3.8/site-packages/colorama/ansitowin32.py", line 162, in write

错误触发于print语句。近期从Python3.6升级至rh-python3.8，当前使用Django3.2、uWSGI2.0.20版本，此前未出现此类问题。
