Hi everyone, from today, NIS.exe, when system is idle (screensaver on) write continuosly to

c:\Programdata\Norton\[very long number]\NIS_21.6.0.32\Product\STAMPDNode.dat.

In 3 hours NIS.exe wrote over 3,2 GB of data. Windows 7 Sp1 32bit NIS 21.7.0.11.

Same problem reported here: https://community.norton.com/en/comment/6258381#comment-6258381

Last time the problem disapperead itself after a live update which contained "wax rules" and "sonar update".

Could Symantec try to track the issue and verify which update cause this massive write on c:\Programdata\Norton\[very long number]\NIS_21.6.0.32\Product\STAMPDNode.dat ?

Thanks in advance.
