FWIW, we've been doing this for several years without issue. Master
serve (and robot control host) is Solaris, and it's also a media server.
We've got another Solaris media server and a Win2K media server. They
play fine together.

Not around here it doesn't. It may take a reboot a month but that's
about it, if it's even that frequently.

We're using Emulex HBAs in our Windows system. We had a Solaris media
server running with a JNI card but its replacement is using an Emulex.

We've never seen whatever issue you're referring to.
