STM32F429+(DCMI)+Timeout

Hello ,
i have a STM324x9I-EVAL board with DCMI interface.

I can grab images correctly for 5-7 times, after that i get Errorcode 3 HAL_DCMI_ERROR_TIMEOUT.

how can i recover from that?
i tried :
- suspend, startDCMI
-stop, startDCMI
-deinit, initDCMI ,startDCMI

i have a main cyclus which polls for the error with low repetition and after the error occurs it always enters the errorroutine again. No interrupt is fired for DCMI at all after it.

the camera is still sending data, i confirmed that with osci.
