UIP Exception-Task Id not found

[Guest]

Hi All,

we are using UIP 2.0 along with ASP.Net 2.0, and we are keepin our UIP state
in SQL 2005, Many times while accessing the state my ASPX pages get a
unhandled error like :

UIP Exception, Task Id not found <some task id>

Any one can please give some idea ? I have checked the UIP code , this
exceptions come while deserialization !!
