STM32WB CPU2 stops after several connect/disconnect sequences

I expirence very strange behavior on STM32WB. After 6 connect/disconnect sequences, CPU2 stops working. I'm not receiving any IPPC interrupts. Last event I get, before CPU2 stuck, is ACI_ATT_EXCHANGE_MTU_RESP_VSEVT_CODE. I tried to call hci_reset function and then reinit BLE stack, but it didn't help. Anyone has any idea what can cause that problem?

Hello,

Can you give more information about your setup ? Which BLE stack are you using and which version ? Are you using the nucleo board or custom board ?

Best Regards
