Subject SV: JOB [CONTRACT] + Re: Windows + MP2 in a production environment
Date Tue, 21 Nov 2006 08:06:18 GMT

Hi All,

I think we are a lot of windows users experiencing the same problem with mod_perl/apache:
"The famous 3221225477 exit status".
My company will also be willing to donate some money If it will help solving the problem.

BTW. I don't recall using the LibXML library unless it is used in some of the other modules
I use (Template Toolkit).

Best regards
Henrik Schak Hansen

Hey Stephane,

Thanks for zeroing in on the problem libraries. I don't remember using LibXML, but I'll see
if I can replicate the problem as well, in a simplified model.
