why getting AFDataPipe gets different value from PI AF server

It is very weird that AFDataPipeEvents have different values than the values in PI AF server, in my application(windows service).

What I have done in code:

1. subscribe AFDataPipe with IOberservable pattern

2.signup all the attributes required to listen in AF templates

3. start listen the AFDataPipe

4. Get AFDataPipeEvent from Next(AFDataPipeEvent)

When my application runs a period of time, it starts getting wrong data(different than the data in PI AF server. The event data becomes normal when the application is restarted.

It is very strange to me.  I want to figure out why it happens like that. Is it my code issue or PI AF server giving wrong data?
