asterisk users - Feb 2005 - Asterisk hangs the establised calls

<font size="2">Hello all,
<br><br>I have an asterisk 1.0.3 stable instaled on a box.
<br><br>All works fine with this machine, but the only problem i get
is that
suddenly the machine hangs up all the establised calls and we have to
call again.
<br>This problem occurs twice a day and i don not know how to debug it.
<br><br>I read carefully the logs placed in /var/log/asterisk, but I
can not find the reason for this hangs.
<br><br>I have to say that when this occurs, sometimes asterisk
restart, if i
make a "show uptime", I can see that asterisk has recently restart,
but
other times when the same occurs, I can see that asterisk is running
seven hours ago, but our calls was hanged up too.
<br><br>I have to say that automaticaly (By own script) asterisk
restart every night
<br><br>How could i debug that?
<br>Does your Asterisk hang suddenly all the establised calls?
<br>Do you know any command that help me finding the problem?
<br><br>Thanks for your time.
<br><br>Ismael.
