      Hi Sateesh,

      That is usually a sign your server is overloaded.  For a high number of nodes you should be using NMIS 8.7.1 or 8.7.2, then use the polling_summary.pl report to understand if your server is keeping up with the load.

      If polling is not keeping up, you will need to add more threads.

      You can only add more threads if you have enough CPU, Memory and Disk RW capacity.

      You can check your servers load by using top and iotop, review the CPU and memory stats in top and review disk RW in iotop.

      You can tune NMIS8 some information in the following pages:

      NMIS 8 - Configuration Options for Server Performance Tuning

      This describes NMIS9 but good reference for reviewing server performance

      Configuration Options for Server Performance Tuning

      I hope that helps
