My Alpha/LInux UP2000 SMP with 1GB memory is running kernel
2.4.5pre2aa1.
I have been observing some strangeness with Swap usage quite recently
(in fact since 2.4.4). Unfortunately, the kernel was made using
gcc-2.95.2-136.alpha.rpm provided by SuSE-7.0.
The following is the output from "free"
=========================================================================

At this point, the mouse movement crawls down at an unacceptable level.
I
cannot understand that the above showing of 0 free space of swap space
although the sum of all memeory usages is far less than 1GB.
I understand that free swap space may become close to 0 and stay there
for
a while once it ever reached down close to zero. However, it should
back
up some nonzero number if the situation is cleared.
Please tell me whether something is wrong or not with the kernel. If
so,
I think I should back down to Kernel 2.2.20pre2aa1.
Thank you very much.
