[hobbit] Problems with hobbitping when the Network is unreachable (BUG)

[Sebastian]

Forgot to mention that I am using the latest version of hobbitping (snapshot
from 18-Mar-08).

(BUG)



Hi Henrik, 

I rebooted my hobbit server and it lost its default gateway, unbeknown to
me.  The only symptoms of something wrong was a purple in a network test is
was supposed to be doing and a purple in the server's bbtest column.  Now, I
reckon one or other or both of these should have both gone red and not
purple, and the reason that they did not is due to hobbitping going into a
spin:  what looks like a fairly tight loop.  Hobbitping was using quite a
lot of CPU (I saw it at well over 30%) and server/tmp/ping-stdout.1407 was
empty but server/tmp/ping-stderr.5499 was getting many (about 60) "Failed to
send ICMP packet: Network is unreachable" written to it every second.  I
reckon this message should have been in the report of the connection test it
was trying to do (although you could argue that the colour should be clear
and not red, since one doesn't want dozens of alarms for a problem that is
actually on the network-test server).  It took me some time to figure out
what was wrong because hobbit didn't report this problem in any of its logs
(presumably because hobbitping never returned and so bbtest-net never
returned its status) (and hobbitd_client stopped working for some other
reason (core dump) yesterday and, although restarted, remains not reporting
with nothing in the logs).

Kind regards, 

Sebastian
