Re-Logging in / "Attempt to free unreferencedscalar"]

The question may be dumb, but how do I find out about the old paths? And
what would I have to do to move them to new ones?
I used CPAN to install the modules after upgrading to Perl 5.8.3, and the
CPAN-snapshot tells me they are all there.

Do you use modules(DBI, DBD…) from old perl paths?

Any idea?

The output of perl -V seems okay to me:

I created a 5.8.3-symlink to /usr/bin/perl to avoid any confusion
between

the different versions.
I did not use the Red Hat-mod_perl.rpm, but built the mod_perl-1.99_13
tarball.

I’m sorry that you were confused with this sentence. It’s all about DSO
vs static, but not about MP2 stability.

IMHO errors comes from perl mainly.
RH9 does have perl5.8.0. Did you rebuild mod_perl after new perl
install? What version of MP2 do you have? If it’s RH9 RPMs then throw
it

away, in our days you shouldn’t use anything except 1.99_14 or higher.

perl -V?

Not to be anti-progress, but isnt’ mod_perl for Apache 2.x still
in beta. I would give it a try with Apache 1.3.31 and mod_perl 1.29.

Hi out there,

having installed RT 3.2.0 with Red Hat 9 Shrike, Apache

2.0.50/mod_perl2,

Sendmail 8.12.8, Perl 5.8.3 I am still running into problems,

(1) Everytime a web browser “touches” the site, tail -f

/var/log/messages

will produce a whole bunch of messages like this:

Jul 12 13:49:05 salvador RT: Attempt to free unreferenced scalar: SV
0x96e7c84 at /usr/local/rt/share/html/Elements/Quicksearch line 24.
Jul 12 13:49:05 salvador RT: Attempt to free unreferenced scalar: SV
0x9637474 at /usr/local/rt/share/html/autohandler line 24.
Jul 12 13:49:07 salvador RT: Attempt to free unreferenced scalar: SV
0x96e9f20 at /usr/local/rt/share/html/autohandler line 24.
Jul 12 13:49:08 salvador RT: Attempt to free unreferenced scalar: SV
0x971bea4 at /usr/local/rt/share/html/Elements/SelectMatch line 34.

I don’t know if this does any harm, but I’d like to know what it

means

anyway…

(2) After I have logged out and then in again (same user or not, no
difference), RT is kicking me out and showing the login screen every

time I

try to call upon a menu. Only closing down the browser on the client

machine

and restarting it will solve the problem.

What’s going wrong? Sorry if it’s something simple, but I’m an
expert

In CPAN shell you can use force command.

force test DBI

if OK then
force install DBI

In archives there is threads about such problems.
As variant you can rebuild perl with same config, but without old paths
in INC.
use CPAN ‘autobundle’ command to get current module list snapshot.
