VM ware Server 2.0 is slowing down Windows Terminal Server 2003 after about 6 days...

I am running VM-ware server on a quadcore server with 8GB using 64bit Windows Server 2003.

After about 6 days system performance starts to be very slow. I am running a terminal server on guest machine and its like it degrades my internet connection to 64kbps instead of 50 Mbps. An other guest is running a web server and performance on FTP http is hopeless.

Earlier I was running VMware 1.6 with no problems at all and have an other server running 1.8 with no problems.

Any ideas what the problem is?

    Could it be that your host operating system is somehow being the cause. What else does your host service do? I have to say that I don't like VMware Server 2 and I preferred VMWare Server 1. It could be that VMWare Server 2 has a memory leak or something hence it causes your's VM's to halt - but one would have thought that this would be rare nowadays.
    On another note, can I ask you you choose to use VMWare Server instead of say ESXi (which is also free) to host your VMs? Choosing ESXi would ensure that you get the most out of your hardware and you would also save yourself the cost of the Windows 2003 OS License which you could use else where?

    Thank you for your reply.

    My host operating system is not doing anything else but running VM-ware. I have been thinking about ESXi too, but I can not get any confirmation that my hardware would work with ESXi. My problem is also that I can not move my virtual machines back to version 1, while trying to install ESXi.

    I have also tried to stress the server to provoke the degrading of performance, but have not succeeded. I have to wait about 6-7 days, and then I will have to reboot...

    I have found that Vmware server 2.0 is a processor hog.  I have not pin pointed why but moved back to server 1.08 and been happier in my test environment.

    If you are considering moving to ESXi, I highly recommend you check out the VMWare HCL before such a commitment.  You don't want to find out that your hardware is not supported after you have started the installation.

    Problem is that I can not move my guest hosts back to 1.0.8 since I the VM hardware is not compatible. Do anybody know a way to convert it back from version 2.0 to 1.0.8?
