[Kroupware] Seg Fault during installation

[Bill]

Stephan

Yes its possible.  I checked top and I was running kinda high, so i
rebooted.  Once I came back up, I started turning off services I could
do without.  

I still couldnt install without a segfault.  top reported 233460K of ram
available and 1534136 of swap before attempting to install.

This box has 384M ram and 1489M swap partition.  What are the min memory
requirements for this system?  I couldnt find a number in any of the
docs online.

thanks
