I just removed the connection with my test account (which had been connected with CB Auto Welcome), sent a new request which I then accepted with the test account. On my main account, I still don't see any post of the test account. The other way around, the posts of my main account disappeared on my test account's activity wall when connection removed, and showed up again when a new connection was established. So CB Auto Welcome is probably not the cause after all.
And yes, the thought just occurred to me as well that maybe it has something to do with the large amount of connections. I have nearly 2500 connections, mainly because most people accept the automatic connection request.
No php/sql error appears on the screen though. When I switch error reporting on, none of the errors/notices that appear seem to be related to this issue:
