I have a number of FreeBSD systems running under various versions of VMWare products (ESX, ESXi, Server) and can tell you that this is almost certainly a problem on the host side. It can happen if the SAN is timeouting, for example if it's doing disk scrubbing too diligently, etc. or the FC connections are problematic. Try to get the vmware admin to look at the logs more closely both on the host and on other machines hosted on the same VMWare instance or the same SAN. Btw. which SAN product is it?
