its a type of shared memory, you can turn it off by commenting it out of your /etc/fstab. some programs which use that kind of shared memory will no longer function. I have been running my laptop without /dev/shm for over a month now day in and out without the slightest glitch(though my laptop is debian :) ). You can always turn it back on if you need it. This won't completely eliminate shared memory, there is another kind, System V ??(read a brief article about this on IBM's site last week) which seems most apps use, and this is not affected by turning off the /dev/shm stuff. I don't think when it allocated 500MB that it's actually using it, I think it just instructs the kernel that there is up to 500MB of this kind of shared memory available. I am not sure if when some of that is used it shows up in 'df', because apparently nothing I use uses that kind of shared memory so I can't test. nate -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED]?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
