Yes, auto-expiry was already disabled.

I hadn't heard of that before, so have now added it. It only happened
a few times (at least that I noticed), and only under extreme load, so
I also suspect it was a locking issue?

Yes, have now done this, but the document referenced is cut down too

I'm also having problems with the AWL instructions from that document.
It seems I don't have an existing AWL to convert to be imported into
