asp.net - Session get expire before the time set -

i getting log out .net application before session expired.we using web farms inproc settings, tried login using individual link each server,still kicking out of application within 5 -6 minutes.

somtimes session last till 1 hours. happening our applciation deployed in webserver,. in mid of doing somthing, application kicking uu out , says login again.
