I have a ETL job running, which is scheduled for every 5 minutes from 1 AM to 9 PM everyday. Generally it takes 10 minutes to execute that package, But unfortunately the first cycle i.e. at 1AM is taking 2 hour or 3 hours or 4 hours from last few days . When I see the Reports from integration service catalogue I see following message:
Data Flow Task:Information: The buffer manager failed a memory allocation call for 65520 bytes, but was unable to swap out any buffers to relieve memory pressure. 74 buffers were considered and 72 were locked. Either not enough memory is available to the pipeline because not enough are installed, other processes were using it, or too many buffers are locked
and then:
Data Flow Task: The buffer manager has allocated 65520 bytes,even though the memory pressure has been detected and repeated attempts to swap buffers have failed
