Hello all,

I developed a PHP application which use slapd. Sometimes, I have the message "Can't contact LDAP server", but sometimes it works (almost half the time)

Just before it hangs, I see the following message: -------------------------------------------------- daemon: epoll: listen=8 active_threads=0 tvp=zero daemon: epoll: listen=9 active_threads=0 tvp=zero daemon: epoll: listen=10 active_threads=0 tvp=zero connection_read(20): input error=-2 id=1530, closing. connection_closing: readying conn=1530 sd=20 for close daemon: removing 20 conn=1530 fd=20 closed (connection lost) daemon: activity on 1 descriptor daemon: activity on: --------------------------------------------------

Sometimes, I also see theses messages: -------------------------------------------------- slapd[9635]: connection_close: deferring conn=1582 sd=22 connection_input: conn=1593 deferring operation: binding --------------------------------------------------

I use : - debian 6.0.5 - slapd 2.4.23-7.2 - OpenSSL 0.9.8o 01 Jun 2010

I don't see at all where the problem can comes from because it works half the time. Can anyone help me?
