Best Regards, George I suppose you could add some debug code to where you believe the calls to waitpid should be/are The way I read it, without threads it should be in src/main/radiusd.c:631 in cvs 20060124 Joe - List info/subscribe/unsubscribe?

No. See radiusd.c, look for waitpid(). That code reaps the zombies when there are no threads. I have checked the source, waitpid() is really there but I don't understand why zombies add up when 1.0.1 is compiled without threads. I found a solution (compiled 1.0.1 with --with-threads option) and it works for me, but I'd like to help freeradius team (if I can) to find the reason why it's broken (at least in my environment) in newer versions.

The way I read rad_fork(), it will call reap_children() every time it is called. But there's not necessarily anything calling reap_children() inbetween. This means that zombies will only live forever on servers without traffic. You should probably read the comment in front of reap_children() in src/main/threads.c. I believe it explains why this design was chosen. Bjørn - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html

Debian + Exec-Program = Zombie process
Hello, I am using Debian GNU/Linux 3.1, libc6 2.3.2.ds1-22. I have compiled freeradius 0.93, 1.0.1, 1.0.5, 1.1.0 in turn with the following options: ./configure --prefix=/usr/local/freeradius --without-threads compilation/installation went fine, radius started up fine. /usr/local/freeradius/etc/raddb/acct_users content: DEFAULT Acct-Status-Type == Stop Exec-Program = /usr/local/bin/test.pl /usr/local/bin/test.pl content: #-- #!/usr/bin/perl exit(0); #-- as soon as I send accounting stop packet to radius, test.pl executes and becomes a zombie.
