This is a problem of global destruction of Embperl's application object.
This will not shown when you use the 2.0b9 distribution, but when you run
xsbuilder on your own, for example because the sources are taken from the
cvs.

SessionX on Debian Sid

2003-11-16 Thread Andre Landwehr
Hi Angus,
after stracing apache2 segfaults on a page containing nothing
but a http redirection, which started to happen a few days ago
due to a new apache2 version in debian sid, I found that
rebuilding SessionX eliminates the problem. All my other pages
still worked ok, so you might not have stumbled about that yet.
I think it might still be a good idea to release a new version of
the SessionX package.

Andre

RE: Locks on sessions database

2003-11-16 Thread Vijaya Dasari
Hi, 

It was the problem with the Apache::DBI.

We were loading this Apache::DBI module along with other Perl modules
(used for the global variables).
These Perl modules access the database.

So when the apache starts the parent daemon, it already has connections
to the database(created by these perlmodules).

And we used httpd2-prefork, when apache creates forked processes these
connections (from Apache::DBI Connections) are also forked. And in this
way the same database connections are shared between the forked
processes and they are trying to access the session data (at the same
time) creating deadlocks.

We removed the preloading of modules in the apache parent daemon (from
httpd.conf) and it solved the problem.

So now I guess the Database connection pool (Apache::DBI) is created for
each forked process of the Apache.

Thanks,
Vijaya.
