Description Karsten Hopp 2008-02-11 16:34:16 UTC 
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):
openoffice.org-2.4.0-6.2.fc9



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

somewhat overly aggressive alright
Comment 2 Karsten Hopp 2008-02-13 13:09:50 UTC 
Created attachment 294768 [details]
pstree output
Comment 3 Karsten Hopp 2008-02-13 13:10:21 UTC 
... that's with 2.4.0-7.1.fc9
