RAK7249 GPS troubleshhoting

Issue:GPS and buffer issue

Setup:7249 fw r209

LoRa® Server:

Details:My RAK 7249 fw r209 using the TTN backend has started to fail. It connects to TTN with basic station. But the GW GPS shows as disconnected and the system log is showing GPS S2E failed to send GPS event no buffer space errors. If I switch to the LoRa mode to packet forwarder it seems to work after a hard reboot.
