session expired within 10-20 seconds while working on Visual Administartor.

session expired within 10-20 seconds while working on Visual Administartor.

Details: In VA, each dispatcher and Server process have four components:

kernel, Interfaces, Libraries and Services.

While working on Kernel in VA of dispatcher or Server, I'm getting 'session expired' after every 10-20 seconds.

I'm not getting the same 'session expired' problem while working on interfaces, libraries or services.

After 2-3 minute of wait, again i'm able to work on kernel but again after 10-20 seconds, session get expired.

Pls suggets to resolve this problem. We are on SP level 20.
