Hi, I have a machine AMD Sepron LE-1150 ASUS M2A-VM 1GB RAM ECC 2x SATA 300GB in a RAID 1 (gmirror). 7.0-RELEASE-p2 AMD64 generic kernel it was doing backups via bacula to an external disk USB 2.0 SATA disk, and it was working well. (GLabel) /dev/ufs/BackupDisk I changed to rsnapshot recently, with the External HDD in glabel + gjournal (/dev/da0s1.journal -> /dev/ufs/BackupDisk) and it will reboot the machine roughly 30 minutes after the rsnapshot starts via CRON. If i run rsnapshot without CRON, eg. via the command line it works fine. (I'm compiling the new kernel p6 whilst doing an rsnapshot via the command line) I have changed the time it does the rsnapshot, from 3AM (reboots at 3:30-3:40AM roughly) to 4:30AM (reboots at 5AM roughly). So its nothing running on the system doing it. If i remove the rsnapshot from the CRON, the computer stays on and doesn't reboot. Its not the power supply, and the computer is on a UPS and the UPS log hasn't reported any blackouts. (There are 2 other servers that doesn't turn off so its not a blackout). I left gstat and top running L(q) ops/s r/s kBps ms/r w/s kBps ms/w %busy Name 0 0 0 0 0.0 0 0 0.0 0.0| acd0 0 125 125 4164 5.5 0 0 0.0 29.9| ad4 0 0 0 0 0.0 0 0 0.0 0.0| ad4s1 0 0 0 0 0.0 0 0 0.0 0.0| ad4s2 0 125 125 4164 5.6 0 0 0.0 30.5| ad4s3 34 142 71 9079 9.4 71 8697 212.0 99.3| da0 34 142 71 9079 9.6 71 8697 213.5 99.3| da0s1 0 0 0 0 0.0 0 0 0.0 0.0| da0s1c 7 135 71 9079 9.7 64 8184 33.0 85.1| da0s1.journal 0 125 125 4164 9.2 0 0 0.0 39.8| ad6 7 135 71 9079 9.7 64 8184 36.2 91.9| ufs/BackupDisk 0 0 0 0 0.0 0 0 0.0 0.0| ad6s1 0 0 0 0 0.0 0 0 0.0 0.0| ad6s2 0 125 125 4164 9.3 0 0 0.0 40.4| ad6s3 0 0 0 0 0.0 0 0 0.0 0.0| mirror/gm0s1 0 0 0 0 0.0 0 0 0.0 0.0| mirror/gm0s2 0 125 125 8328 9.9 0 0 0.0 43.9| mirror/gm0s3 0 0 0 0 0.0 0 0 0.0 0.0| mirror/gm0s1a 0 0 0 0 0.0 0 0 0.0 0.0| mirror/gm0s1b 0 0 0 0 0.0 0 0 0.0 0.0| mirror/gm0s1c 0 0 0 0 0.0 0 0 0.0 0.0| mirror/gm0s1d 0 0 0 0 0.0 0 0 0.0 0.0| mirror/gm0s2c 0 0 0 0 0.0 0 0 0.0 0.0| mirror/gm0s2d 0 0 0 0 0.0 0 0 0.0 0.0| mirror/gm0s3c 0 125 125 8328 10.2 0 0 0.0 45.2| mirror/gm0s3d last pid: 18829; load averages: 0.29, 0.45, 0.50 up 1+01:31:23 05:01:50 64 processes: 1 running, 63 sleeping CPU states: 16.5% user, 0.0% nice, 25.2% system, 3.0% interrupt, 55.3% idle Mem: 69M Active, 436M Inact, 395M Wired, 44M Cache, 108M Buf, 3944K Free Swap: 2048M Total, 308K Used, 2048M Free PID USERNAME THR PRI NICE SIZE RES STATE TIME WCPU COMMAND 18634 root 1 -4 0 15224K 2244K getblk 0:45 9.47% rsync 18633 root 1 98 0 18296K 4576K select 0:45 4.69% rsync 18375 root 1 8 0 20556K 8412K wait 7:20 0.00% perl 4447 root 1 -64 0 7656K 2036K RUN 1:21 0.00% top 4321 root 1 8 0 11784K 2008K nanslp 0:45 0.00% gstat 18627 root 1 96 0 15224K 2596K select 0:36 0.00% rsync 4219 evxadmin 1 96 0 32936K 3220K select 0:07 0.00% sshd 3800 evxadmin 1 96 0 32936K 3164K select 0:06 0.00% sshd 18629 root 1 96 0 32868K 3964K select 0:04 0.00% sshd 18628 root 1 96 0 23764K 7664K select 0:04 0.00% ssh 851 root 1 96 0 12476K 1832K select 0:04 0.00% nmbd 1788 root 1 96 0 10576K 2812K select 0:02 0.00% sendmail 1147 root 1 96 0 24456K 2404K select 0:01 0.00% nmbd 1346 root 1 96 0 22224K 2504K select 0:01 0.00% nmbd 3957 evxadmin 1 96 0 32936K 3220K select 0:01 0.00% sshd 1800 root 1 8 0 5736K 1032K nanslp 0:01 0.00% cron 1754 root 1 8 0 5736K 980K nanslp 0:00 0.00% cron 1557 root 1 8 0 5736K 980K nanslp 0:00 0.00% cron 1387 root 1 8 0 5736K 980K nanslp 0:00 0.00% cron 1192 root 1 8 0 5736K 980K nanslp 0:00 0.00% cron 4646 root 1 96 0 36968K 4892K select 0:00 0.00% smbd 775 root 1 96 0 4684K 1064K select 0:00 0.00% syslogd Nothing else seems to be running.
