Running Leopard 10.5.4 with as supplied Apache2 and PHP5. PHP5 is enabled, and php.ini edited to reserve 128 M memory. System memory is 2 GB with 1 GB free. PHP -i command validates that the memory setting is read. Bitweaver install does not believe it and still tells me I need more memory. I can not install Bitweaver now. I had installed Bitweaver successfully under OSX 10.4 using compiled from source Apache2 and PHP, but I want to stick to the Apache and PHP that came with Leopard. Any ideas?

I sacrificed a chicken and it cleared up somehow. don't ask how.

perhaps you forgot to reboot apache... and eventually caused a restart.
