S32K SDK LPUART Stuck Servicing IRQ Handler

Team,

 

I have a customer that is using LPUART in the SDK.  They get into a situation maybe after two minutes after running where the S32K stops transmitting because the LPUART_DRV_IRQHandler keeps running continually.  It continually enters the handler sees that there is no transfer happening and exits and then repeats.

 

Thoughts?
