James Peach commented on TS-1822:
---------------------------------
This seems to be gerund way off track. {{proxy.config.system.mmap_max}} does
not set any sysctls. It sets the {{M_MMAP_MAX}} malloc option when using the
glibc allocator. For what that does, see
http://man7.org/linux/man-pages/man3/mallopt.3.html.
My view is that we should just remove this or hardcode the value. I can't
imagine an operator be able to sensibly tune this.
> Do we still need proxy.config.system.mmap_max ?

> A long time ago, we added proxy.config.system.mmap_max to let the
> traffic_server increase the max number of mmap segments that we want to use.
> We currently set this to 2MM.
> I'm wondering, do we really need this still ?
