In my initial PR (sparc64 r261798),

 http://www.freebsd.org/cgi/query-pr.cgi?pr=187080

I said that rsync was triggering this panic.
While true, I now see that there's more to it.
I disabled the rsync, and the cron jobs.
Still I get exactly the same panic every
night at 03:02:

# grep Dumptime /var/crash/*
/var/crash/info.0:  Dumptime: Wed Feb 26 10:10:51 2014
/var/crash/info.1:  Dumptime: Thu Feb 27 03:02:14 2014
/var/crash/info.2:  Dumptime: Fri Feb 28 03:02:29 2014
/var/crash/info.3:  Dumptime: Sat Mar  1 03:02:25 2014
/var/crash/info.4:  Dumptime: Tue Mar  4 03:02:01 2014
/var/crash/info.5:  Dumptime: Wed Mar  5 03:02:05 2014
/var/crash/info.6:  Dumptime: Thu Mar  6 03:02:11 2014
/var/crash/info.last:  Dumptime: Thu Mar  6 03:02:11 2014
# 

This is likely triggered by one of
the daily periodic scipts,
after about 1 min from start:

# grep daily /etc/crontab
# Perform daily/weekly/monthly maintenance.
1       3       *       *       *       root    periodic daily
#

but which one?

Please help

Thanks

Anton
