Thanks for the info! Do files contributing to buffers contribute to cache at the same time? > > What wonders me it the memory usage of Xfree86.

This would explain a lot! My card has afair 128 MB, accounted as 512 MB plus 15 MB adds up to 527 --- plus some other memory actually used, but swapped out, plus maybe a little memory due to leaks. > That doesn't mean X doesn't leak, of course ;-) The problem might > just be that resource leaks in X programs cause memory leaks in the > X server. Hm, they shouldn't do that ... GH -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
