After upgrading from 2.0.x do the subj on a Sun 630 server a strange effect appeared.
Just after boot, the server works perfectly. It is not a very fast one (2 40MHz CPUs), but runs NNTP server, web server and still can be used as a workstation with KDE desktop. But after working for a week or two, something happens. It becomes extremelly slow, it does non-stop swapping and opens a new terminal window during a minute or so. As ps shows, NONE of the processes becomes much larger during this week. But total memory+swap usage grows from 60 to 120 megabytes. And total memory usage by processes and shared libraries, as reported by "memstat" utility, is much less than actual memory usage (that is, "memory used"+"swap used"-"buffers" from /proc/meminfo). It seems that this kernel has some memory leaks ... Any ideas ?
