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.

Yes, right.

Yes, that's normal for 2.4. As soon as you run into swap it will eat
more swap space and keep it also if the load is smaller. This makes
overall swapping faster.

Doesn't have anything to do with tmpfs/shm fs.
