Re: too many files open

[Jim <jim@webstarts.com>]

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.
