Re: (ITS#4379) test008-concurrency hangs

[ivan.lago@ifom-ieo-campus.it]

I have the same issue and i did extensive test: the problem never  
arise on i386 machines but it always arise on amd64 machines.

Here is the output of uname -a of machines i run the test on:

FreeBSD xxxxxx 5.4-RELEASE-p8 FreeBSD 5.4-RELEASE-p8 #0: Wed Nov 16  
14:30:10 CET 2005     root@xxxxxx:/usr/obj/usr/src/sys/GENEBOX  i386
this i386 machine passed the test.


FreeBSD xxxxxx 5.4-RELEASE-p13 FreeBSD 5.4-RELEASE-p13 #0: Tue Apr  4  
15:28:11 CEST 2006     root@xxxxxx:/usr/obj/usr/src/sys/NODE5  amd64
and
FreeBSD xxxxxxx 5.4-RELEASE-p8 FreeBSD 5.4-RELEASE-p8 #0: Tue Dec 27  
12:14:23 CET 2005 root@xxxxxxx:/usr/obj/usr/src/sys/CAINO  amd64
those amd64 machines didn't pass the test.

on all machines openldap was compiled with the same options and  
without gcc CPU optimizations.

On amd64 machines the test008-concurrency always hangs and bumps the  
CPU usage of slapd up to 99% and the directory becomes unresponsive.
