[Asterisk-Users] Asterisk causing server to hang ... any hints?

[beonice]

I am trying to set up a simple Asterisk server. All
it's going to do for now is to act as my voicemail
box. I've got a DID from Voicepulse, and am using IAX
(I'll get to SIP someday when I want to circumvent the
phone company for long-distance, but for now I'd be
happy to get a trial version of Asterisk running).

So far, I've managed to set up voicemail.conf,
extensions.conf and iax.conf so that incoming calls
are answered and a voicemail can be left. Initially I
did not have a handler for the timeout case, and
Asterisk would complain about the missing handler and
occasionally would crash the server after several
messages had been left (I'm the only one testing it,
and the server has nothing else running, just
Asterisk), requiring a hard reboot. 

To avoid this, I put in a handler for the timeout.
Now, Asterisk crashes the server as soon as I leave
myself a message! This is irritating. Hard reboots
everytime someone leaves me a voicemail is not going
to be something I can trust if I go on vacation
(hopefully someday soon).

Any ideas what I am doing wrong?

Here's the change I made to my extension file (this
used to crash occasionally):
[old-context]
exten => 7777,2,VoiceMail,u7777
exten => 7777,3,Hangup
exten => 7777,102,VoiceMail,b7777
exten => 7777,3,Hangup
exten => 7777,103,Hangup


[new-context] ;; crashes all the time!
exten => 7777,2,VoiceMail,u7777
exten => 7777,3,Hangup
exten => 7777,102,VoiceMail,b7777
exten => 7777,3,Hangup
exten => 7777,103,Hangup
exten => 8888,1,Playback(transfer,skip)
exten => 8888,2,Ringing
exten => 8888,3,Wait(2)
exten => 8888,4,VoiceMail,u8888
exten => 8888,104,VoiceMail,b8888
exten => 1001,1,Ringing
exten => 1001,2,Wait(2)
exten => 1001,3,VoicemailMain
exten => _NXXNXXXXXX,1,Background(beep)
;exten => _NXXNXXXXXX,2,SayDigits(${EXTEN})
;exten => _NXXNXXXXXX,3,Goto(testdtmf|s|1)
exten => t,1,Ringing
exten => t,2,Hangup
exten => i,1,Ringing
exten => i,2,Hangup
exten => a,1,VoicemailMain,EXTEN
exten => a,2,Hangup

I thought that using the 
exten => t,2,Hangup and the
exten => i,2,Hangup
would cause Asterisk to hang up on timeout, but
obviously I misunderstood. By the way, what _does_ the
'a' handler do, anyway? I believe 'i' is for invalid
key and 't' is for timeout. I'm not sure what 'a'
does.

The last time I tried to leave myself voicemail,
here's the output I got. And yes, it crashed. I've got
Asterisk running at a level of 4 in terms of
verbosity, i.e., I start it with /usr/sbin/asterisk
-vvvvcp

At this point, the server itself seems to hang. I can
do nothing but a physical reboot of the machine.

HELP.

Thanks,
BeOnIce.
