In our datawarehouse we execute a MERGE query in a storedprocedure in order to synchronize our datawarehouse every night.

Our database server is running Sql-server 2008

During the execution of the stored procedure we receive te following exception:

java.sql.SQLException:Time-out occurred while waiting for buffer latch type 4 for page (1:3939774), database ID 17.

In the eventlog we see several messages with the following format:

What does this mean and what actions should we take to resolve this problem?

Note: I am a developer and not a system administrator, so I don't know what information is needed to answer this question.
