Re: [mp2] Possible bug with "PerlOptions +Parent" with mod_perl 2.0.4 and mod_perl 2.0.5 (Ubuntu packages)
[In reply to]

Hello, may be I've found the root cause of the problem: it seems due to the
apache2-mpm-prefork package, since if I install the apache2-mpm-worker the
same configuration is working as expected!
I can reproduce this in a sistematic way.
Any idea about the reason of this ?
Thanks,
Luca
