Using FlexCAN with RXFIFO DMA stops TX

I run FlexCAN transmit and receive in parallel continuously. If I configure the receive to use FIFO and DMA after some point the transmission stops. It looks like the transmission was started but I get no interrupt from the transmit mailbox. If I configure the receive to use mailbox or FIFO without DMA everything works fine. Is this something that anyone saw before?
