David, /var/log/syslog contains the calibration timeout messages; /var/log/messages contains the Underrun! messages... but anyway, that's what "sort" is for...
In answer to your question, they are often synchronized: Starting with a sample at 07:54 yesterday: the 1st Underrun happens at 07:54:11, same time as a calibration timeout. the 2nd Underrun happens at 18:23:44, some 4 minutes after the last calibration timeout and 1.5 minutes before the next one the 3rd Underrun happens at 18:25:03, same time as a calibration timeout the 4th Underrun and 5th happen at 18:25:04, same time as a calibration timeout the 6th Underrun happens at 18:26:43, same time as a calibration timeout the 7th Underrun happens at 18:28:43, same time as a calibration timeout the 8th Underrun happens at 18:28:44, same time as two calibration timeouts Hmm maybe I should have said they are most often synchronized!
