<P><FONT SIZE=2>I believe this is related to the load, there are always calls in our test.</FONT>
<BR><FONT SIZE=2>Attached is a part of /var/log/messages file with SysRq memory info - in</FONT>
<BR><FONT SIZE=2>case you can see something in it. The box was rebooted 06-16 17:08 and</FONT>
<BR><FONT SIZE=2>the problem occurred 06-17 11:36.</FONT>

<P><FONT SIZE=2>> As far as SMP and single T400P - we'll try and report the results</FONT>
<BR><FONT SIZE=2>> but the idea was to go with as high density as possible ...</FONT>
</P>
<P><FONT SIZE=2>Right, I'm just trying to narrow down the problem. I'm theorizing that</FONT>
<BR><FONT SIZE=2>the problem is some sort of spinlock deadlock. Does it only occur if</FONT>
<BR><FONT SIZE=2>there is activity or even if the lines are up but no calls taking place?</FONT>
</P>
<P><FONT SIZE=2>> What do you think of using hyperthreading - should we enable or disable it</FONT>
<BR><FONT SIZE=2>> for the box running asterisk?</FONT>
</P>
<P><FONT SIZE=2>We use hyperthreading but have not run tests longer than a few hours on</FONT>
<BR><FONT SIZE=2>those machines.</FONT>
</P>
<P><FONT SIZE=2>> What about -DCONFIG_ZAPTEL_WATCHDOG ? Can it help and how to use it?</FONT>
<BR><FONT SIZE=2>k</FONT>
<BR><FONT SIZE=2>Likely will make no difference in this situation.</FONT>
