E (1867354) BT_BTC: btc_gattc_cback transfer failed
E (1867454) BT_HCI: host_recv_pkt_cb couldn't aquire memory for inbound data buffer.
assert failed: host_recv_pkt_cb hci_hal_h4.c:552 (0)

Is it memory leak?
BT controller can drop packet?
Firmware reboot is unexpected, any idea to fix it?
Thank so much!

Maybe. It surely indicates that you're out of RAM/heap. You application may be using too much or failing to free unused heap memory.
