[ros-dev] Bug Check Out of Memory!

[Hartmut Birr]

Hi,

I think your crash has nothing to do with the to many opened handles
from csrss. Currently each created process doesn't free one directory
object (tag DIRT). This is the real problem. One 'ros on ros compiling
run' creates 40,000 process's. Each directory object has a size of 60
byte. With the overhead, it does eat up nearly 3MB of the non paged
pool. Two days are 40 runs (I assume a fast computer). 40*3MB = 120MB is
the limit of the non paged pool.
