Please forgive me for sending this to the user list. I'm not on the
development list (where this belongs) and I don't want to lose what might
be valuable info. If a developer can forward this to the appropriate list
or people, I'd be grateful.
I would also encourage all us users to NOT respond so it doesn't turn into
a useless noise thread.
*********
Conditions
Myth is running FE/BE on xena, in the Manage Recordings menu, doing
nothing that I am aware of. No HD access light except the system pulse.
I had two CLIs on my laptop ssh'd in for some poking around, but nothing
was going on on either.
I got the following kernel message on both CLIs. AFAICT, both the BE and
FE are still running w/o any further error.
While the message appeared in both CLIs, one bounced out of the connection
and the other did not.
