I recently noticed strange message in the logs: | +++ /tmp/security.YBOfj4NZ Tue Dec 27 03:10:48 2005 | +calcru: runtime went backwards from 226760439 usec to 226756967 usec for pid 612 (sendmail) | +calcru: runtime went backwards from 226760439 usec to 226756967 usec for pid 612 (sendmail) | +calcru: runtime went backwards from 226820020 usec to 226816978 usec for pid 612 (sendmail) | +calcru: runtime went backwards from 226820020 usec to 226816978 usec for pid 612 (sendmail) What could be reason for it? Could this indicate possible break-in (it was in security log), or is more likely a hardware/software error? (I'm seeing this message for the first time.) The OS is FreeBSD 6.0 RELEASE (sendmail is the one provided with FreeBSD). PS. Not sure if this have anything to do with it (the message mentions CPU time, not the clock), but I'm running a ntp daemon, to synchronize time... -- Best regards, Derek mailto:takeda@takeda.tk http://www.takeda.tk -- Smash forehead on keyboard to continue.....
