FTDI J2xx library Issue


In one of my demo applications I am trying to use j2xx.jar library for communication. Everything works smooth but suddenly i am start getting below error:

Write date to sink failed.

Mostly this error is defined in catch block inside “extractReadData” of Process request worker.

Once this error occurs in application there is no communication happening.

Can you please suggest something on this context. As i am completely gets stuck in this.
