ADC'value can't be updated after exit from stop mode

Now I'm using STM32F103RE and system will enter stop mode with a periodic RTC wakeup routine.

But sometimes when system exites from STOP MODE, the adc's value can't be updated correctly, especially when system enter STOP MODE for a long time.

OCZ, there will be a periodic RTC routine wakeup to feed WDG.

After exit from STOP mode, I re-init system clock using the example code's ''SYSCLKConfig_STOP()''. All the other peripherals work well but the ADC.

The ADC uses DMA.

So somebody can give me some advices?
