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.

This parameter is changed in /etc/system on a sun 2.8 box, which then
requires a reboot to apply it. In my experience, I've generally had to bump
some of those default system parameters up in Solaris, as any number of
programs I've worked with seem to run into those and similar issues.
As far as what you should set it to, I would do some research on it.
Sunmanagers.org's listmail would be a good spot to check, I'm sure someone's
asked for recommendations on it before, and there's a lot of very
knowledgeable people in that group.

Ken,
When you have "Too many open files" errors in ANY of your logs this is
usually indicative of an OS problem. I am not that familiar with Solaris so
I am not sure how the underlying kernel allows for more or less processes
along with files to be opened and closed for such processes. You really
should check with someone that knows SUN fairly well that can look at this
issue. But I can tell you that it is not a Legato issue.
