Subject: Fix: do not flag consumer as disabled on relayd comm failure
X-Git-Url: http://git.efficios.com/?p=lttng-tools.git;a=commitdiff_plain;h=9e21835385dae360737a08a6119cf870b68f44f6

Fix: do not flag consumer as disabled on relayd comm failure

A relay daemon may be temporarily unavailable (e.g. not launched yet,
or simply a network error). In such a case, it is not necessary to
mark the consumer as bad since the error is not related to the
consumer daemon itself.

This change lets the user try to create a channel later without
having to restart the session and consumer daemons.
