Hi All,
I am wondering if anybody experienced the same problem as me. I just
finished creating a few linux vm each with 512mb vmemory on my Xenexpress
4.0.
After a few days the memory usage on each vm gradually increasing from 10%,
and a few days later it became 30%. On my linux guest I only start mysqld
service with minimum services on.
Any help or feedback would be appreciated.
Below is the top output from one of my vm:
top - 18:16:32 up 2 days, 3:05, 1 user, load average: 0.00, 0.00, 0.00

This is typical behaviour for linux. The linux kernel will attempt to
allocate all available memory for disk caching, you will eventually see
memory usage rise to ~90% and then sit around that point.
Inside top type ''m''. This will add a memory summary at the
top.
