Thus sounds like the out of memory killer. You should find at least a few entries in the system log detailing what was killed and why.<br><br>Where this is logged on a Debian system, I don&#39;t know.<br><br>-- <br>Deanna Earley<br><br><div id="htc_header" style="">----- Reply message -----<br>From: &quot;Keith Williams&quot; &lt;keithwilliamsnp@gmail.com&gt;<br>To: &lt;users@lists.bitfolk.com&gt;<br>Subject: [bitfolk] Nagios warning<br>Date: Wed, Apr 11, 2012 10:42<br><br></div><br><div>Yesterday I was away from the computer and came back to see a series of Nagios alerts, related to DNS. It appears that the Bitfolk dns servers were unable to update a zone from my server. I was unable to login to my server, so went into Xen. It was unable to either shutdown or reboot. When I opened a console window, it was impossible to read as text was scrolling up continuously and rapidly. I had no alternative but to Destroy. A scary option, but within seconds it did the trick and all is running well now.</div>
<div> </div><div>I have scanned the logs this morning trying to find out what had gone wrong. I realise it was something going haywire and consuming all the resources, but please could anyone give me pointers on how to determine what it was that was behaving so badly?</div>
