...that is, I AM seeing scheduling errors in 1.2.1.2. And you say that you DON'T see the scheduling errors in 1.2.1.2. Curiouser and curiouser.
Sorry; either I was unclear or you misunderstood me but I suspect that in this case 1.2.1.2 introduced some issues that weren't previously there; especially the issue that you are reporting here doesn't materialise in that form in 1.2.1.1 for me.
I hope that clarifies?
Yours,
