ISSUE TYPE
COMPONENT NAME
dnf
ANSIBLE VERSION
ADDITIONAL INFORMATION
I'm running ansible with mitogen. Ths was failing on Fedora with processes running out of file descriptors. This is because mitogen runs each tasks in the same process and dnf was not closing file descriptors. Eventually it would run out. See mitogen-hq/mitogen#280 for more information.
