SUMMARY: /usr/lib/utmpd: file descriptor limit exceeded

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
