I have, what is hopefully a final update to this issue(s).

we upgraded to xoa version .99 a few weeks ago and the problem has now gone away. we suspect that some changes were made for timeouts in xoa that have resolved this , and a few other related problems.

@jshiells Why don't you open a support ticket and allow us to take a look at this for you?

@Bastien-Nollet Thank you, great explanation!
