T4240 rman stop working

Hi!

I used the t4240's DPAA to transfer data between the rapidio and the 10-gigabit network. But occasionally there are problems. rman was unable to process the received data and the software did not report any errors. But when I looked at the registers associated with rman, I found that the Message Manager Status Register (MMSR) had a different value than when it was working normally. OHWC (Open hardware contexts) is 0x10. I tried to change the GEN value of the MMRCAR register to 0x18 maximum. However, the fault persists. The OHWC still reaches the maximum value 0x18. How can I avoid this situation? Open hardware contexts are fully occupied.

Thanks a lot!
