via mmap() up around the shared library area. Previously the directory was allocated from space from it's own memory pool. Because of the way it was being extended on processes with large malloced data segments (ie: inn) once the page directory was extended for some reason, it was not possible to lower the heap size any more to return pages to the OS. (If my understanding is correct, page directory expansion occurs at 4MB, 12MB, 20MB, 28MB, etc.) I was seeing INN allocate a large amount of short term memory, pushing it over the 28MB mark, and once it's transient demands hit 28MB, it never freed it's pages and swap space again.) I've been running this in my libc for about a month... Also, seperate MALLOC_STATS from EXTRA_SANITY.. I found it useful to call malloc_dump() from within INN from a ctlinnd command to see where the hell all the memory was going.. :-) I've left MALLOC_STATS enabled, as it has no run-time or data storage cost.

This install procedure is ALPHA code, and `--{__________)
may very possibly *DESTROY* the contents of your
ENTIRE DISK! Please do not proceed with this installation
unless you've adequately backed up your data first!
If any errors occur during this installation, you can see them
by toggling over to the alternate screen - type ALT-F2 to switch
over, ALT-F1 to switch back to the install screen. The debugging
output on the second screen may be very valuable to us in understanding
your bug report, so please be sure to take note of it when reporting
any failures in the installation! Thanks!
Menus and scrolling output windows may be traversed with the arrow
and Page Up/Page Down keys. To suspend the installation at any point,
hit ESC twice. Hitting TAB will move the focus to different controls.
If you've ever dealt with a DOS installation, you'll know how to deal
with this.
For a more complete description of what's new in this release, please
see the release notes.
For more documentation on this system, it is recommended that you purchase
the 4.4BSD Document Set from O'Reilly Associates and the USENIX Association.
ISBN 1-56592-082-1 We have no connection with O'Reilly, we're just
satisfied customers!
Have fun, and please let us know of any problems you encounter with
this release!
