Hello,
I got a few responses. Someone suggested that it looked
like a workaround for an old version of Solaris, and they
suggested removing it. I did end up removing the MAX_FDS line
from the /etc/default/utmpd file.
Here are a couple of the other responses:
"Use rlim_fd_cur and rlim_fd_max parameters. You can get more information on
these parameters in Solaris Tunable Parameters Reference Manuals... Let me
know if you need these, I can send you the PDFs as well."
" I have SCAN_PERIOD=300 as the only entry in my /etc/default/utmpd file.
According to a summary I found, the values
SCAN_PERIOD=30
MAX_FDS=3
might help. If not, try modifying the S88utmpd script to remove the
utmp and utmpx files from /var/adm, and then create new ones before
starting utmpd:
rm /var/adm/utmp /var/adm/utmpx
cp /dev/null /var/adm/utmp
cp /dev/null /var/adm/utmpx
chown root /var/adm/utmp*
chgrp bin /var/adm/utmp*
chmod 644 /var/adm/utmp*
"
"Two entries in /etc/default/utmpd are supported:
a.. SCAN_PERIOD - The number of seconds that utmpd sleeps between checks
of /proc to see if monitored processes are still alive. The default is 300.
b.. MAX_FDS - The maximum number of processes that utmpd attempts to
monitor. The default value is 4096 and should never need to be changed.
"
Thank you for your help!
Nicole
