Use ~? for help] swap_pager: indefinite wait buffer: bufobj: 0, blkno: 3864, size: 12288 and things started moving again, in /var/log/messages: Jan 16 03:27:35 store-02 kernel: swap_pager: indefinite wait buffer: bufobj: 0, blkno: 3864, size: 12288 but the REAL time is 7hs ahead!, so time stood still ? and now, of course we get: Jan 16 03:54:19 store-02 ntpd[38163]: time correction of 25216 seconds exceeds sanity limit (1000); set clock manually to the correct UTC time. I will now reboot, and try a newer kernel and check, but any insight will be very helpful, thanks, danny
