Folks, this doesn't happen very often so I thought it best to pass on the following information. VMware recently sent out a recall notice about two of their VMware ESX Server patches that had been made available for download. The patches in question are the 2.5.4 Patch 6 (Build #41630) and the 2.5.3 Patch 9 (Build #41618). Both have been recalled in the interest of stability for ESX Servers.

Hence, multiple virtual machine power-offs, suspensions and VMotions may cause the host to run low on memory.”The fix has been made available for immediate download in the form of new patches (ESX Server 2.5.4 Patch 7 and ESX Server 2.5.3 Patch 10).
