unable to join the environment

[jehan procaccia <jehan.procaccia@int-evry.fr>]

didn't got answer to my question about "unable to join the environment"

[root@corbeau /var/lib/ldap/int]
$ /usr/local/jehan/db-4.1.25.NC/bin/db_stat -m
db_stat: unable to join the environment
db_stat: DB_ENV->open: Resource temporarily unavailable

cf thread below in that mail ...

However, I've found discussion on the cyrus imap mailling list which 
talk about:
" The problem is caused by your DB4 using posix threads which RedHat has 
badly
mangled in RH 9.0." cf:
http://www.irbs.net/internet/info-cyrus/0305/0463.html

could this be the right direction to search for ?
