I intend to set MaxMemFree by default. The reason is that some
modules use a lot of memory for a few requests (e.g. mod_dav,
mod_php). With MaxMemFree disabled, the allocators will grow to the
size necessary to serve the most memory intensive type of request
and never shrink again. And since we have one allocator per
connection (on event) or one allocator per thread or process (on
worker/prefork), this can add up to insane amounts of memory. As
pointed out by a recent bug report, it is easy to make mod_dav use
50MB for a propfind request. Multiply that by 1000 allocators...
I think 4MB could be a reasonable default for MaxMemFree.
+1.
