Task bbnet terminated by signal 6 🔗 link

Greet,

OpenBSD 3.2 running  hobbit-4.1.1 as server.

Started getting all purple network tests on the display.

I tried restarting hobbit and I see this in the log:

2006-06-08 19:14:05 hobbitlaunch starting

2006-06-08 19:14:05 Setting up logfiles
2006-06-08 19:14:10 Task bbnet terminated by signal 6


I then upgraded to the latest hobbit-4.2-beta-20060605 and still have  the same problem.

Nothing has changed on this box for months..

I read a thread for running with --no-ares, I tried appending that  line to a few CMD lines in hobbitlaunch.cfg with no luck.
I'm really not sure where that goes ;)

Any thoughts?

Thanks,

Lee

Ok, that is interesting. Could you try this:
 - login as the hobbit user
 - run the command "~hobbit/server/bin/bbcmd bbtest-net --debug"

The interesting part of the output is what happens shortly before the
crash.

Also, there ought to be a "core" file from these crashes. If you
could run it through gdb to locate where it crashes, this would
be really helpful. See
  http://www.hswn.dk/hobbit/help/known-issues.html#bugreport
if you're unsure of how to do that.

Disk full ?

OK, hope I did all this right. I have attached a ascii file of the  output from bbtest-net --debug.

Here is the gdb output.

I haven't really gotten anywhere with this. There are no obvious
code errors in the region where it crashes, so the C-ARES problems
are still a primary suspect.

The --no-ares option goes on the CMD line for the [bbnet] task.

[bbnet]
	ENVFILE /usr/lib/hobbit/server/etc/hobbitserver.cfg
	NEEDS hobbitd
	CMD bbtest-net --report --ping --checkresponse --no-ares
	LOGFILE $BBSERVERLOGS/bb-network.log
	INTERVAL 5m

Could you try running with this for a while and let me know if it helps?

Also, check that the Hobbit logfiles do get rotated. Logs larger than 2
GB can cause weird problems in Hobbit 4.1.x.


Thanks,
Henrik

OK, added the --no-ares and still no luck. Signal 6 within a few  seconds after I start hobbit.

/var/log/hobbit is only 53M.

So, I tried to rebuild from scratch. New user and latest version  hobbit-4.2-beta-20060605.

On OpenBSD 3.2 during the gmake install I get the following error at  the end.


chgrp `id -g hobbit` /var/log/hobbit /home/hobbit/server /home/hobbit/ server/* /home/hobbit/server/bin/* /home/hobbit/server/etc/* /home/ hobbit/server/ext/* /home/hobbit/server/web/* /home/hobbit/server/www/ gifs /home/hobbit/server/www/gifs/* /home/hobbit/server/www/menu / home/hobbit/server/www/menu/* /home/hobbit/server/www/help /home/ hobbit/server/www/notes /home/hobbit/server/www/html /home/hobbit/ server/www/wml /home/hobbit/data /home/hobbit/data/*

What do I need to do to fix?

Do you have any "dns" or "dig" tests in your bb-hosts file ? Hobbit will
use ARES for those, even though you did add the --no-ares option.

Running "bbcmd bbtest-net --debug" will give some more clue about what
it does when it crashes. Just the last screenful of output.

I think you hit <enter> in response to the    What group-ID does your webserver use ?
question during ./configure. Check the Makefile and see what the
"HTTPDGID" setting is.

I have another report that an upgrade of the C-ARES library fixed crashes in bbtest-net. So that is what I'd like you to try next:

* Grab the file http://www.hswn.dk/~henrik/c-ares-cvs.20060621.tar.gz
  and save it in the bbnet/ directory in your Hobbit source tree. * Do an "rm -rf bbnet/c-ares/; make clean"
* Change build/Makefile.rules - the line with     ARESVER = 1.2.1
  should be
    ARESVER = cvs.20060621
* Rebuild with "make; make install"
