Excessive virtual memory activity prevents NIM from making progress
Excessive disk I/O traffic is interfering with paging I/O
        Recommended Actions
        Examine I/O and memory activity on the system
        Reduce load on the system
        Tune virtual memory parameters
        Call IBM Service if problem persists
