Hi,<br><br>We've been experiencing a situation in which our library server seems to suddenly go unresponsive, without much warning. In looking at logs, I see a couple things.<br><br>First, in lonnet.log I see some entries like the following distributed throughout the log file. I don't know how to interpret these entries, but they seem to indicate something isn't quite right:<br>

<br>When the system seems to go unresponsive, lonnet.log has the following entries:<br><br>Sun Oct 7 12:07:17 2012 (21568): <font color="blue">WARNING: Trying to get resource data for smarkoe at csm: con_lost</font><br>

<br><br>I strikes me as very much not good that my library server has been marked "DEAD". Any ideas on what can cause a host to be so marked? It doesn't appear to be load based, as it seems to have happened at a variety of load levels, including pretty low. Any help you can provide would be greatly appreciated.<br>
<br>Thanks,<br>Todd<br>
