shared memory problem

[Admin Mailing Lists]

I've been using the 2.2.x series successfully, latest i used
was 2.2.19pre7.
Today i upgraded to 2.4.1-ac9 and noticed that shared memory shows 0.
I searched the list archive briefly and someone said the stats have been
broken since sometime in 2.3, but my system also shows my swap being used
up a great deal (100MB whereas i'm rarely using more than 5MB (and that
only at loaded times, which this isn't))

this server is dedicated for apache web serving, and CONFIG_TMPFS is not
configured in/any shm fs mounted. I didn't have this in 2.2 either.

here's my /proc/meminfo and ipcs info..any help or advice is appreciated.

ipcs -lm

------ Shared Memory Limits --------
max number of segments = 4096
max seg size (kbytes) = 32768
max total shared memory (kbytes) = 8388608
min seg size (bytes) = 1

ipcs -m shows many segments used by apache servers.
