On most platforms, the file descriptor limit can be significantly
increased. I suggest you try that.
The file descriptor limit is 8192 for the userid slapd runs as and
OpenLDAP was built with that FD_SETSIZE (env
CPPFLAGS="-DFD_SETSIZE=8192"). I have verified that other
applications running as the slapd userid can grab up to 8192 file
descriptors. However, slapd maxes out at 1024 file descriptors every
Aug 17 16:35:46 sparky slapd: daemon: 1024 beyond descriptor
table size 1024
This is on Red Hat ES 3.0.
Is there some other build option that should be included in order
enable a larger file descriptor limit?
Thank you very much for your response and time.
The operating system itself may be limiting the file descriptor limit that
a user process can use. I suggest reading the man page on "sysctl" and
perhaps tweaking sysctl.conf.
