There are three distinct groups of possibly relevant threads, to do with interactions between ssh-agent and one of ServerTree [no idea what that is] GitHub gnome-keyring-daemon Also, if (my own case), I use gpg-agent maskerading as ssh-agent, and _it_ has the 100% problem sometimes. Of course, none of this is relevant if the OP's problem with ssh is not co-occuring with ssh-agent chewing up an entire processor. ht -- Henry S.
