migrating about 700GB of data via cifs/robocopy from 1TB OF 2.2 box to 2TB OF
2.2 box, each with latest (pre-vtl) patches. target box is Geode NX 1750
(Athlon XP core) with 2GB of ram on SIS chipset board. Intel Pro1000 and 3Ware
7506-12 only additional componenets in system. boot and phy storage is on
11-drive raid5 array. target vol is 1TB with snapshots on an 8-day 24hr roll.
about 2 days into it i check back in and it is moving at snails pace (1-2MB/s
on the man-in-the-middle migrating box running the robocopy) and about 450GB
copied...

i got to access the share from another system and takes forever. i then past a
small file into the share (to test if that will even work) and after several
minutes i get an error (pseudo quote as i couldn't get a screen shot) "could
not copy to location because path is too long"
i ssh into the box and load is 4+ with disk wait time through the roof,
everything else at idle usage except swap completely full. I tried to run a ps
auxww to capture a log. Meanwhile, back at the ranch...
additional access attempts fail, ssh session trying to get ps output
non-responsive, robocopy job log begins reporting "destination inaccessible" -
basically system has grenaded.
i connect a monitor to the console and oom-killer info dumps are spewing to the
screen about one every second or two.
I checked the messages and found an asortment of ldap secrets errors (not sure
about that) but the only entry i found that seemed suspect was:
Feb 1 22:28:38 hopper smbd[5714]: [2007/02/01 22:28:38, 0]
lib/util_str.c:safe_strcpy_fn(603)

bringing back up, snapshot report shows:
