A number of my guests running under Linux seem to be stalling with a Fatal exception. Are we maybe taxing the incoming server a bit much? Or is this actually somewhat normal processing? :) Exception Message: A std::exception was thrown. Can not get data (Additional Information: [frontier.c:799]: No more servers/proxies. Last error was: Request 26 on chan 1 failed at Tue Mar 17 15:45:46 2015: -6 [fn-socket.c:112]: connect to 128.142.156.169 timed out after 5 seconds) ( CORAL : "coral::FrontierAccess::Statement::execute" from "CORAL/RelationalPlugins/frontier" ) CMS_8510_1426111757.078819_0 http://boincai05.cern.ch/CMS-dev/result.php?resultid=25309 Whenever I peek in at these systems, the server is partially idling, which is unusual with them running BOINC to consume all those spare cycles. The VM Guests with this type of error on the console seem to be waiting for something and not doing any actual work. With the virtualbox guest only consuming about 10% of a core. Just wanting to share. Reno, NV Team: SETI.USA |

This is probably because the CMS job queue is empty - be patient (:-)) |

This may be that the proxies we use for "frontier" (experiment conditions database as far as I understand it) are down or overloaded. From what I see, we're hardwired into using proxies at Rutherford Appleton Lab in Oxfordshire; this may not be an optimal ultimate configuration, we shall probably have to move to a more-intelligent regional-based distribution. Not sure about Ben's guess that we're out of WUs, there seem to be enough there (unless someone has just refilled the cache). |
