Phillip, Thanks for your reply.
First off a bit of CPAN wierdness. With perl -MCPAN 'install Sys::HostIP' you get version 1.0 (07 Jun 2000), rather than the latest version (1.3.1 29 Sep 2003), something to do with the change of owner (five->bluelines). Unfortunately 1.0 is the only version which doesn't use local %ENV (...and hostip() was the old method not the new one). http://search.cpan.org/~five/Sys-HostIP-1.0 (07 Jun 2000) http://search.cpan.org/~bluelines/Sys-HostIP-1.3.1 (29 Sep 2003) Did you check how many httpd processes you had running? ps -A | grep httpd | wc -l You will only get the Seg fault or Bus error when a process comes round for recycling. For convenience you could reduce the number in httpd.conf: <IfModule prefork.c> StartServers 1 MinSpareServers 1 MaxSpareServers 1 MaxClients 150 MaxRequestsPerChild 0 </IfModule> I have actively tested this problem on 6 different machines (different OSs and mod_per versions), and am therefore fairly sure it exists. I was doing some testing as I am looking to upgrade to mod_perl 2.0. I have 30+ machines running 1.99_09 where local %ENV isn't a problem.
