SysVSemaphoreLocker.pm problem

[Markus Schranz <sc...@pressetext.at>]

Hi,

I seem to be not the only one that has problems with Semaphores in
the apache-mod_perl context:

We run a redhat6.2 server and have installed a apache_1.3.12 with
mod_perl_1.24 and
mod_php4.01pl2 (linked statically, since DSOs do not work as posted in this
group)

We want to use Apache::Session::DBI to TIE a %session Hash for each user
session to a database (sessiondb/sessions). After installing all necessary
perl modules
(why are they not included in the CPAN Bundle::Apache?) I call

PerlModule Apache::DBI

in the httpd.conf file and after this

PerlRequire apache_handler.pl

which initializes the database access and does the cookie handling, that
writes
session info to the %session hash, tied to the DB.

On startup, everything is fine, after the call to the first Mason component,
I
get the %!*&!%/$§ message :-(

I am sure, you have got this problem earlier (I am spending now the second
day on it &%§$*%% ggrr :-(((

Help very much appreciated,

thanks
