Mavros: Terus jatuhkan Pesan dan katakan TX queue overflow， saat mempublikasikan topik ke mavros/setpoint_raw/local

Tim yang terhormat,
Bisakah kalian memberikan bantuan atau saran tentang ini.

Saya tidak tahu di mana harus men-debug ini, saya menggunakan kode yang sama, tetapi kesalahan ini baru muncul di hari kedua, sepertinya aneh.

Detail masalah

Saya menggunakan mode OFFBOARD untuk mengontrol Drone untuk terbang di dalam ruangan, saya memiliki sensor kedalaman dan tag visual sebagai umpan balik dan menggunakan kontrol closeloop kecepatan. Tapi ketika saya publish msg ke /mavros/setpoint_raw/local di 100hz selama beberapa detik, error muncul, dan sepertinya drone tidak bisa menerima msgs, saya test beberapa publish rate dan pixhawk yang berbeda(2 dan 4) errornya masih ada.
Saya benar-benar tersesat. mohon petunjuknya.

Prosedur peluncuran saya:
terminal1: roslaunch mavros px4.launch
terminal2: rosrun offboard drone_control.py

px4.launch saya
