Hi,
this may probably be not fully related but I see from time to time a
strange behavior of ssh-agent (running in the background and initially
started by keychain launched in .bashrc) : the agent is running wild (25%
of cpu and never responding). It seems to occur (not systematically) when
network is disconnected and reconnected (this is on a laptop often removed
from the docking system). Do you have any idea how to diagnose the issue
more precisely?

Regards
