Checked ulimit and processes are not the issue here. Rsync never has
more than 15 instances running and even accounting for children and
other processes they wouldnt approach the process limit. The error
ddoes seem to be with btrfs as I cant ls the file system while this
condition exists. Ls also returns "too many files open". Btrfs sub
list also shows the same too many files open condition. Actually, there
should be no files open after the script has failed (the script runs,
just reports the errors). Something either reports files as being open
or is holding them open, and a remount flushes this and the fs is back
to normal. Very confusing.

Good morning Btrfs list,
I have been loading a btrfs file system via a script rsyncing data
files
from an nfs mounted directory. The script runs well but after several
days (moving about 10TB) rsync reports that it is sending the file list
but stops moving data because btrfs balks saying too many files
open. A
simple umount/mount fixes the problem. What am I flushing when I
remount that would affect this, and is there a way to do this without a
remount. Once again thanks for any assistance.
Are you sure it's a btrfs problem? Check "ulimit -n", see "help
ulimit" (assuming you use bash).
