Why isn't "(ulimit -d 1000; firefox) &" working?
- by MaxB
I'm trying to limit the memory usage of firefox to prevent it from stalling the whole system with problematic web sites.
I tried, in bash:
(ulimit -d 1000; firefox) &
This should limit the memory usage to 1000kB. Then I opened YouTube, and noticed, in top, that firefox is using 2.6% of the memory, or about 200MB, and not crashing. Clearly the limit is being ignored. Why is that, and how can I enforce it correctly?
