Bridge crashes labelling, rating, writing metadata on windows share

We started having really tricky behaviour with MacOS High Sierra devices, using our normal Windows 2012 r2 file servers.

If you apply any sort of meta data changes to a file in Adobe Bridge - including rating or labelling, it stops responding as soon as you click away from the current folder/try to do something to another file in the same folder etc.

Even more troubling, it seems to crash finder too - so you can look around the folders you've recently connected to (presumably the folder cache) but trying to go anywhere else on the server or refreshing those folders fails.

Even worse it causes the machine to fail to restart properly, so your only recourse is a hard reboot.

It sounds like Bridge is causing some sort of cascading failure that spreads far beyond it - but it definitely starts with Bridge: we haven't found a way to replicate the behaviour with any other program.

Has anyone else come across this? It happens on several different spec, different manufacturer, file servers and on all of our High Sierra macs. All with the most recent version of Bridge.

Not good...!
