Hi all,

All my servers and workstations running a 2.6.21.5 kernel hanged exactly
when the date shift from june 30th to july 1st.

On my monitoring system every single station running a 2.6.21.5 kernel
stoped responding exactly after midnight on the date shift from June
30th to July 1st. Although, stations still running 2.6.18 to 2.6.20.11
worked flawlessly.

I first tought there had been an electricity outage but two of my
servers (dell PE 2950 dual-quad core) on UPS in our server room also
hanged:
Jun 30 23:55:01 urpdev1 /USR/SBIN/CRON[31298]: (root) CMD ([ -x
/usr/lib/sysstat/sa1 ] && { [ -r "$DEFAULT" ] && . "$DEFAULT" ; [
"$ENABLED" = "true" ] && exec /usr/lib/sysstat/sa1; })
Jul 3 11:54:03 urpdev1 syslogd 1.4.1#17: restart.

I could not get anything on any of the 20+ consoles... All the systems
hanged at around the exact same time... When the date shifted from June
30th to July 1st in UTC ...?

Any clue any one?

No problems over here with plain 2.6.21.5 on x686

You could just reset the date back on one of these machines and
check the transition again... and see if it was really the kernel
who crashed.... and check your cron configuration.
