[Voyage-linux] Watchdog Not Rebooting.

[Robert Rawlins - Think Blue]

Hello Guys,

 

I've been doing some more testing on this problem this morning and not
really getting anywhere. Even when doing a completely clean build of 0.6.0,
the first thing I do after booting up is edit the watchdog.conf to watch a
pid file which doesn't exist, the watchdog daemon logs that it's unable to
find the pid file however the watchdog doesn't kick in and reboot the
system.

 

We're somewhat reliant on the watchdog for our systems and I'm keen to solve
this. We're running on an ALIX 3d2 however I've tested on other ALIX boards
and also with version of 0.5.2 and still get very unreliable results.

 

Am I doing something wrong? What can I do to test this further?

 

Cheers,

 

Rob

Hello Guys,

 

I've got a voyage 0.6.0 build running on an ALIX board, today I replace the
CF card after we had a data corruption issue. I tested this card in other
ALIX systems earlier this week and the watchdog appeared to work great! I
also know than this current board with the old CF card also had a working
watchdog.

 

All I can tell you at the moment is that the daemon is logging to
/var/log/syslog like so:

 

Jun  4 18:48:22 voyage watchdog[3188]: still alive after 36 interval(s)

Jun  4 18:48:22 voyage watchdog[3188]: was able to ping process 3130
(/var/run/obex-data-server.pid).

Jun  4 18:48:22 voyage watchdog[3188]: was able to ping process 3162
(/var/run/thinkblue.pid).

Jun  4 18:48:22 voyage watchdog[3188]: was able to ping process 2911
(/var/run/dbus/pid).

Jun  4 18:48:22 voyage watchdog[3188]: was able to ping process 3011
(/var/run/mysqld/mysqld.pid).

 

Now, say I kill one of these processes, I then get a log entry like so:

 

Jun  4 18:49:52 voyage watchdog[3188]: still alive after 45 interval(s)

Jun  4 18:49:52 voyage watchdog[3188]: was able to ping process 3130
(/var/run/obex-data-server.pid).

Jun  4 18:49:52 voyage watchdog[3188]: cannot open /var/run/thinkblue.pid
(errno = 2 = 'No such file or directory')

 

I then get no further log entries from the watchdog, however the system does
not reboot!

 

Can someone help me diagnose and solve the issue? I'd really appreciate that
J Like I say I know for sure that:

 

A)     The ALIX board is functional, it was working on the old CF card.

B)      My /etc/watchdog.conf is just fine, it's the same config I use on
other systems.

C)      My /init.d/watchdog is just fine, this has only been modified to
have '-v' to log the output.

 

Thanks chaps,

 

Rob
