Somehow, I suspect you're just being sarcastic;  if, however, you're serious,
then you're somewhat mistaken as to the meaning of the "stable" label.

Following on from your original message:

  "Wen you do a search on the ./tests/test-db/master.log file you will see
  '**** got 0 of 0' on every search!"

Having just built and tested OpenLDAP 1.2.7 in an attempt to recreate this
problem, I find that "./tests/test-db/master.log" doesn't contain any instance
of the phrase "got n of n" at all.  Could you perhaps provide some context for
this line?  My tests all pass such that upon completion, this phrase does not
appear in master.log

A search of the OpenLDAP source (for RE /got.*of/) shows the string:

  *** got %ld of %lu so far

in the file "./servers/slapd/connection.c";  according to the source, there
should be a line just before this one, along the lines of:

  ber_get_next on fd %d failed errno %d (%s)

At a guess, if this line appears before the "got n of n" in your master.log,
then the errno should give you some clue as to why the searches are failing.

As above - clearly I'm not suffering the same fate as you with the test suite,
so you'd have to provide additional information (such as a few more lines from
master.log, without quoting the whole file).

This definitely doesn't happen for me;  I suspect it's due to the less than
stellar threads implementation in Linux (I'm using Solaris).  There has been
some talk about pre-emptive threads being a problem for OpenLDAP 1.x on
OpenLDAP mailing lists.

With all due respect to Andrew Davison - I don't see his name as a core
OpenLDAP developer, and his presence seems pretty small in a search of all the
OpenLDAP mailing list archives;  just what is it that he plans to "release"?
Is there some other piece of software in which Andrew may have found a bug?

Kurt didn't "blame" you for "misusing the software" - he merely stated the
obvious, given your less than accurate/complete "analysis" of the problem;
clearly, if there was a fundamental backend database problem then why hasn't
it affected my OpenLDAP 1.2.7 test, or my 2.0-devel system (with over 20,000
entries across two database backends)?

>From your original message:

  "I hoped to find a working version in the cvs tree but currently it
  doesn't compile."

Precisely what is "it" (ie., using what CVS tag did you download source)?  My
test system (derived from CVS) compiles and runs fine.
