Hi folks,
I can't help but wonder if this is because of the link-time
optimization that was enabled rather recently (with v88, if memory
serves).
Perhaps you can investigate this?
If you just want to mitigate it, there's two ways of achieving it:
You can either use limits(1) or use resource control via rctl(8).
The second option does mean that you either have to limit the
memory use of your user account, or run Firefox in a jail, but
using [1] makes that relatively easy.
Yours,
Daniel Ebdrup Jensen
