MemoryPages/sec is high - Could Service Broker be responsible?

    We have SQL Server 2005 SP3 CU4 installed on a 64 bit server. I am trying to determine why the MemoryPages/sec is pinning about every 5 minutes. I don't believe it is a job. I know it isn't backups. Could Service Broker be responsible?

    Do you see BROKER_TASK_STOP event wait times?

    select * from Sys.dm_os_wait_stats
    This is how it looks
    wait_type waiting_tasks_count wait_time_ms max_wait_time_ms signal_wait_time_ms
    BROKER_TASK_STOP 6244857 919642203 10000 51640
    What does this mean?
    Is this good or is this bad?

    Could this be an issue for the MemoryPages/sec?

    I was reading http://sql-server-performance.com/Community/forums/t/15407.aspx
    Can the network affect the Memorypages/sec? When I run performance monitor and look at the Network Utilization on Windows Task Manger/Networking Tab, I do see a correlation. However, I am not sure I understand. Is there a web page that explains this?
