Hi!
To increase the FDs available for DS, edit the Configuration --> Performance Settings and increase the no. of FDs available for DS. please check if you havent done this.
I faced the similar problem. Increased the system limit(/etc/system) and DS setting, but was still recieving the error message time to time, which disappears automatically, when FDs get freed. The server is quite a busy LDAP server.
Can someone comment how can i see the actual Fd utilisation on a Solaris 8 system.
I have been checking like:
ls -l /procs/fd | wc -l
and by:
ls -l /procs/pid-of-slapd/fd | wc -l
But always find the Fds in use to be quite lesser than the limit specified 4096.
Thanks for sharing.
Cheers!
