Hello Ron, thanks for your reply. I think your second option is what causes the problem. In the meantime I could find out that HP-UX uses a four-quadrant memory allocation scheme where the data, text and shared memory segments are apparently restricted to approx. 1GB for 32-bit processes. According to the linker man page, it is possible to change this so I think this is nothing that could be fixed without recompiling perl! Maybe it would be best to go to 64-bit directly...
