RmFlush: Failed locking DbWriteSem

hiwe installed a virtualized Domino 8.0.2 64 Bit and replicated our old DBs from existant Domino 7 Server.

Since Monday two large Databases are corrupted, no Documents can be saved and Database-Compact Or Database New Replica will always cancelled. We installed now Domino Server 8.0.2 Fix Pack 1 Windows 64 English and it seems we can do a New Replica of one of the corrupted Databases.

BUT…

We puzzle about another Console-Error on different Databases and we don’t know if there is a correlance to the problem described above:

RmFlush: Failed locking DbWriteSem for ‘d:\Lotus\Domino\Data\OneOfOurDatabases.nsf’ [span = 25818K recLSN = 550000001C048FF9A10117B80-FFFF27C1FDB24A755010117B90] : 86:26

Req(Status=Granted Mode=SIX Class=Manual Nest=1 Cnt=1

   Tran=10871238 Func=N/A  [0AC0:0002-0ED8])

What is that - what can we do??

Please help
