You can mostly fix this problem by imposing a maximum to the amount of
RAM used by a process.
E.g. you can add a file `/etc/security/limits.d/10-mylimits.conf` which
contains something like:
# Limit processes's memory use to a max of 4GB so that a single
# runaway process can't bring the machine down.
* hard rss 4096000
* hard data 12000000
I guess with 32GB of RAM you can afford to use a higher limit than 4GB,
but the idea is to make sure that a single runaway process can't eat up
all the memory and make the whole machine unusable.
[ Firefox is still perfectly usable on my i386 machine, so 4GB per process
*should* not affect normal use. ]
