Summary:                    Corrupt Memory Issue - with Valgrind Trace
Description: 
Hi,

Have a CentOS 5 system running Asterisk 1.6.0.9 (have tried more recent
builds too but know this version well) and it is becoming unstable when
loading IAX2. Once the module is loaded, the asterisk console prompt no
longer appears unless connecting remotely, and even then it only gives
output to some commands.

Without IAX2 loaded the system is stable for a few hours, or shall i say a
few calls.

I know that there can be an issue with corrupt memory, but i am not sure
what this points to. I have created a valgrind trace and hopefully this may
shed some light on what is at fault.

I should not also astcanary is tweeting. Everything else on the stable,
webserver etc are running fine and stable. The problem has persists through
multiple reboots and disk checks.

Cheers
Leo

Interesting, I don't think DB1 supports any inherent consistency checking.
The DB code is tightly coupled with Asterisk, and so it should  be possible
to check that we're only reading a reasonable amount of data/rows first.
I'm now worried that I don't have a copy of this DB any more, and am
presuming it's the only thing that would help a BDB1 expert resolve this. I
will persevere in finding this again.
