Subject: Shared Memory Problem

Greetings,

A simple question, I believe ...

I built my own 2.4.15-pre7 kernel today and have a problem - I can't start
httpd. Whenever I try I get the following messages:

Nov 20 18:53:35 walnut httpd: Ouch! ap_mm_create(1048576,
"/var/apache-mm/mm.1529") failed
Nov 20 18:53:35 walnut httpd: Error: MM: mm:core: failed to acquire shared
memory segment (Function not implemented): OS: No such file or directory

Which kernel CONFIG symbol I have set wrong?

Thanks.

David

P.S. I do have CONFIG_TMPFS=y and the df command shows:

Filesystem 1k-blocks Used Available Use% Mounted on
/dev/sda6 4111268 1564388 2338040 41% /
/dev/sda1 15522 4266 10455 29% /boot
none 63736 0 63736 0% /dev/shm

CONFIG_SYSVIPC probably. TMPFS is a shared memory file system and posix
shared memory. Apache uses the older sys5 shared memory standard
