I have updated source, server was running ok last week... Any good reason or clues why my calendar server would now hang during startup: exec python /usr/local/src/Twisted/bin/twistd -n caldav -f /usr/ local/src/CalendarServer/conf/caldavd-dev.plist -o ProcessType=Combined 2008-12-08 14:05:57-0800 [-] Log opened. 2008-12-08 14:05:57-0800 [-] twistd 2.5.0+rUnknown (/usr/local/bin/ python 2.5.2) starting up 2008-12-08 14:05:57-0800 [-] reactor class: <class 'twisted.internet.selectreactor.SelectReactor'> 2008-12-08 14:05:57-0800 [-] [calendarserver.tap.caldav.CalDAVServiceMaker#error] Unable to detect number of CPUs: getNCPU not supported on freebsd7 2008-12-08 14:05:57-0800 [-] [calendarserver.tap.caldav.CalDAVServiceMaker#info] 0 processors found.

Thanks in advance, John Berliner
