[asterisk-users] MWI and 1.6.1

Mon Mar 8 16:08:16 CST 2010

Top posting to remain consistent...

Matt,
After doing a little more digging I'm starting to think that it has
something to do with our upgrade from 1.4 to 1.6 (nothing like stating the
obvious). I'm now suspecting that astdb has something to do with it. I ran
strings on astdb which lives in /var/lib/asterisk/ and found references to
messages files inside the DB. Maybe they lived there in version 1.4 but not
in 1.6. Somebody more clueful than me can probably clarify on this. Doing a
dump of the same database doesn't show the  references to those files. Could
this be what is generating the MWI events?

So my thought was to just dump the database in a good state and reload.
Unfortunately trying to load the dump leaves me with a newer version of the
database files that Asterisk recognize. Asterisk uses a very old version 1
of Berkeley DB.

Anyone know how to load a db_load as version 1.85/1.86? I can't seem to
figure it out.

So a couple of questions I have for you Matt...
If you run strings on your astdb file are you seeing references to messages
files in it?

#strings /var/lib/asterisk/astdb | grep -i msg

 and if so...

If you run a db_dump185 on your astdb file do the references go away?

#db_dump185 -p -f /tmp/astdb.dump astdb

Then look at the resulting file in /tmp and see if any references to message
files are there.

At this point I'm completely shooting in the dark but It's the best I've
come up with.

Let me know your results and perhaps we can figure this out.
Thanks,
Dave
