found 835119 0.2.8.2-alpha-1 thanks
I tested different versions again yesterday and today, this time only 0.2.7.6-1, 0.2.8.2-alpha-1 and 0.2.9.1-alpha-1 and I had several "long" standby sessions. The results are again confusing, the 0.2.7 series doesn't seem to have the issue, but it occurs in the 0.2.8 series and also in the version 0.2.9.1-alpha-1 which also worked "normally" one time, as you can see in the complete log of yesterday and today.
