The log has the error ORA-8224 in fetched item.

Has anyone seen this?

Never seen that one :(

Here is the info I found online-

[DEV:bsp]/app/common/home/bsp>oerr ora 8224
[DEV:bsp]/app/common/home/bsp>oerr ora 7224
07224, 00000, "sfnfy: failed to obtain file size limit; errno = %s."
// *Cause: The ulimit system call returned an error.
// *Action: Check errno and contact customer support.

Check the Unix ulimits -

$ulimit
unlimited
$ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) 1048576
stack(kbytes) 392192
memory(kbytes) unlimited
coredump(blocks) 4194303
$ulimit -s

Also check with your Oracle DBA's, I found this info on the Oracle metalink-
