Description Karsten Hopp 2008-02-11 11:34:16 EST
Description of problem:
during a rebuild of openoffice.org I've noticed that one perl process per CPU
was created which in turn runs up to 1 compiler process per CPU. On a 16 CPU
machine this results in up to 256 gcc/g++ process which can bring down a machine
due to an out of memory situation. I've killed the build after it used up 8G
main memory and another 10G swap.

Version-Release number of selected component (if applicable):

Steps to Reproduce:
1. Build openoffice.org on an SMP and watch p.e. with pstree how numcpu*numcpu
processes are created.

Additional info:
There should be only one compiler running  for each CPU, not numcpu compiler
process per CPU
