No handlers could be found for logger “paramiko.transport”

问题

I am running some fabric tasks inside of flask. Flask is running inside of wsgi in apache. Once in a while I get this error in the apache logs:

No handlers could be found for logger "paramiko.transport"

I then have to restart apache for the fabric tasks that are called via flask to work again.

Any ideas here... I'm running Ubuntu 12.04

Fabric==1.5.3

paramiko==1.9.0

pycrypto==2.6

Flask==0.9

Seems like the answer was to add disconnect_all() to all of my fabric functions. Now the problem seems to have gone away.

I found the solution for paramiko from this website: https://translate.google.com/translate?hl=en&sl=zh-CN&tl=en&u=http%3A%2F%2Fwww.ouvps.com%2F%3Fp%3D869

Basically, you just need to add a line

paramiko.util.log_to_file("filename.log")

Then all connection will be logged to the file

Not sure where to put that line in fabric
