In my earlier post in this thread, I included a link to another post which suggested that these are probably coming from a call to deUnRegUserTriggers() in a context file loaded from the .cdsinit. It's unlikely that they're in the bindkeys - unless there's a call to this function in leBindKeys.il or schBindKeys.il - which seems unlikely.
The warnings are benign - although it is bad practice of the PDK to be unregistering the de triggers. This has been shown to break certain tools because they depend upon these triggers. In ancient history (IC446 and before) there used to be a limitation that you could only have one user trigger defined - but this was fixed over 10 years ago. So you really ought to contact IBM.
If you can't track down where they are coming from, and want a quiet life for users (no warnings), you could always add this at the beginning of the .cdsinit before any of the PDK stuff is loaded:
Oh, hang on - you were asking about the "awv" messages (I got confused because you posted about the other warnings in another old thread). The awv warnings must be coming because of a call, somewhere, to an hiSetBindKey on "awv". You'll just have to hunt it down!
Try running "virtuoso -nocdsinit" and then gradually load the files loaded from the .cdsinit - or comment out pieces of the .cdsinit and see the effect. Again, the warnings won't cause any problems in practice.
