Description Martin Kudlej 2010-06-18 12:59:55 UTC

Description of problem:
After submission ~1.2M jobs has scheduler in memory almost 3GB. I think after discussion with developers that It could be possible optimize this huge memory allocation.

Very simple example of job:
Universe=vanilla
Executable=/bin/sleep
Arguments=10
Queue 1000000

Version-Release number of selected component (if applicable):
condor-7.4.3-0.19.el5

Please feel free to change target milestone.

Here are examples that scheduler crash because it reach 3GB of memory which is border of OS with PAE kernel. Please see #603657 #603658
