Hello,

Where exactly do you have the message "too many open files" ?
To verify this issue, if you can isolate the process that displays this 
message, use the following
command to verify the number of open files
pfiles $(pgrep nsrexecd) <-- change nsrexecd by save or savefs or your backup 
command.

Updating the file /etc/system will change the maximum number of open for the 
overall system, which
may be is not the best practice.
The second option is to modify the startup script of the Networker daemons and 
adding at the top
of the script the line "ulimit -n 1024".
By default a process is started with a maximum of 256 file descriptors.
After changing the startup script of networker /etc/init.d/networker, you'll 
have to restart the
daemons.
( cd / && sh /etc/init.d/networker stop && sh /etc/init.d/networker start)
The client daemons nsrexecd will be restart, you can verify that the file 
descriptor limit has
been  updated by typing
pfiles $(pgrep nsrexecd)
As all the backup commands (save, savefs, nsrnmo,...) are initated by the 
nsrexecd daemons, then
will use the same file descriptot limit.


The example here will increase the number of open files from 256 to 1024, if 
you want more you'll
have to update the file /etc/system first.

I've never seen such an issue before...

Regards.
