I am responding in regards to a previous message I sent to Kurt.  Basically,
we were having erratic freezing of the slapd daemon when attempting to make
modifications.  We experienced no problems during reads.  Your reply is below.

I attempting to troubleshoot, I finally installed a non-threaded version of
ldap, and it has since worked without any problems.  At this point, I have no
how to furthur isolate the problems other than what was previously submitted.


Likely the server is running out of file descriptors or some
other resource... which the server doesn't handle well.

You should also look at your client and make sure it is properly
unbinding the LDAP session.

Well, I have looked at the script, and every instance of a successful
connection is followed by a disconnect.  Also, this same script has
no problems against the older 1.2.11 server.

The other thing of note is that there a two scripts I am using.  One
had some bugs, which resulted in incorrect output.  However, it also
was very careful to open and close connections properly.
Unfortunately, with that script, after about 20 to 30 connections, the
server will freeze.

I am baffled by this, and any attempt to debug results in an output
file sever megabytes in size.  Also, is we wait for the server to
cleanup the network connections (takes about 4 minutes), the LDAP
server is STILL frozen and non-responsive.
