slapd freezes

[Alexey Marinichev <lyosha@snowball.ucd.ie>]

I have openldap version 1.1.4 installed from the Debian package.  I'm adding
entries (words from the dictionary) to it with a simple python script.  If, at
the same time, I'm doing the search, say, for words matching `ab*', slapd
freezes.

The result is 5 slapd threads, 2 of them waiting on do_select, and 3 others
waiting on sigsuspend (from ps -l).  The server itself doesn't respond.

Is this a known bug?  Is there a patch for it?

Thank you--
