Session Blocked by another idle session - forum topic by Kishore_1

In View Point , I am observing an IDLE session is blocking an ACTIVE session.On further investigating, I found the blocker session is holding a Read Lock on one of the tables that the blocked session is trying to access.
 

BLOCKED BY

USERNAME UserName 

HOST 1 

SESSION ID 266310918 

LOCK TYPE Read 

STATUS Granted 

LOCKED RowHash DBName.TableName

When i see the session details of 266310918, it is as follows:

STATE   IDLE 

TIME IN STATE 0:40:50 

TOTAL DURATION0:00:00

 
Can anyone explain this: 1) Is the blocker session still executing any query, as its holding up a read lock on a table?
2)If its still executing a query , then how can it be IDLE?
