rlm_perl forking zombies

[david.suarezdelis at telefonica.es]

Greetings,

I have FreeRadius 1.1.0 working on Debian 3.1 on an Intel box.

When using rlm_perl, the authenticate() sub does its job and, eventually,
calls a method to send an email to a certain address before returning OK.

The problem is that this SMTP connection can take longer than wished,
therefore I am forking the SMTP call, so the authentication process can go
on as normal.

The problem with this solution, though, is that--as I cannot wait for the
SMTP connection to be done--the process is left as a zombie. I have,
therefore, used a double forking solution, where the grandfather returns
inmediately to the authorize() function, and the child forks again, and
waits (waitpid()) for the new (grand)child to do the job, so no zombie is
created.

By itself, this works and no zombies are left behind, as expected. However,
when used with FreeRadius, zombies are left behind. I have tried to
'IGNORE' SIGCHLD, to use reaper function (and all the other tricks in
perlipc(1)) to no avail (I am even using Proc::Fork to simplify things so I
am sure I am doing things properly).

Is this a problem with my calling this inside the authenticate() function,
or with rlm_perl, or...? Is this a problem with 1.1.0 and solved with a
later version?

Any help appreciated.

thanks a lot!
david

PS- Perl is version 5.8.4 compiled with threads and ithreads

PPS- has the RLM_PERL module documentation's been improved in more recent
versions, by any chance?
