Let me give an intermediate result:
The test of the -SP1 patch series succeeded.
We started the test of the -SP2 (and mainline) series on Tue, 9th, but had no
success.
We did _not_ find a problem with the patches, but under -SP2 our test scenario
has less than 40% of the throughput we saw under -SP1. With that low
performance, we had a 4 day run without any dropped RPC request. But we don't
know the error rate without the patches under these conditions. So we can't
give an o.k. for the patches yet.
Currently we try to find the reason for the different behavior of SP1 and SP2
