Correct! That is exactly what happens.... I think Sanjay Srivastava has more problems on his side then just memcache....
Everything works ok as said before if memcache is disabled. When enabled there is a 1 min delay. The delay part is strange because before there was never a problem with it. It is not in themes or plugins and as far as i can remember nothing has changed in core since last update to v8.02.
Anyway not my problem :-) Server is using 24cores and 32g ram so it can handle it without memcache
