Pavan, In the Description text you will note that it states "Continuous Transaction Storage is full...". This means that wherever you are storing Purepath data has run out of room based on the disk space allocation you specified. In the client, select Settings -> Dynatrace Server -> Storage. Take note of the settings at the top and compare how much storage you've allowed compared with how much storage is avaialble on that disk. You might want to move your Stored Sessions to another disk, then update the Stored Sessions Directory. Or allocate more space to Dynatrace Storage.
