[Fedora-directory-users] too many fds open

[Craig Ayliffe]

Hi,

Has anyone come across problem with directory server having too many
fds open, which then causes it to not receive any new connections?

Version: Fedora-Directory/7.1 B2005.146.2010
OS: Linux ds01 2.6.11-1.1369_FC4 #1 Thu Jun 2 22:55:56 EDT 2005 i686

One thing I have noticed is a lot of tcp connections owned by the
ns-slapd process, that are suspended in the CLOSE_WAIT state.

# netstat -nap
...
tcp        0      0 ::ffff:10.10.246.31:389
