Jeff,
Steve made a code change that should have resolved this error;
WARNING: ldm_clnt.c:277: Couldn't connect to LDM 6 on rtstats...
and the idd.unidata "No route to host" looks like some sort of route
flapping. I searched through logfiles on other systems I have access
to and can't find a single occurence elsewhere. I don't know what to
think on that one. As for the last error "Couldn't connect to LDM 6 on
idd.unidata -- Connection refused", I may have the answer. We're
running a LVS cluster (for idd) and using the persistent flag to
satisfy the "Are you Alive" query from the downstream to the server
back to the same real server. If one LDM cluster node starts
misbehaving, the downstream will disconnect and reconnect and keep
being redirected back to the same failing node. We're working on our
logic to detect when a node has gone bad and drop it out of the cluster,
but clearly, we're not quite there yet.
Could you forward or make available via ftp/web your ldmd.log for today?
