Leif Hedstrom commented on TS-1822:
-----------------------------------
Right, it should call it with M_MMAP_MAX, increasing it from the default 64k to
whatever the setting is in records.config.
I'm positive that this feature was added to solve a problem where it looked
like ATS ran out of memory; When allocating RAM for the cache, it used to
allocate tiny mmap areas. But as far as i can tell, this doesn't happen any
more. However, it sounds like the reclaimable freelist thingie needs a lot of
mmap areas?
> 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 ?
