Wifi TX errors

I have many devices communicating over ESP-NOW and after some seemingly random amounts of time I get these errors:
E (2263070) wifi: esf_buf: t=3 l=64 max:8, alloc:8 no eb
W (2263080) wifi: alloc eb len=64 type=3 fail, heap:160840
Does anyone know what these errors mean?

Mesh internal communication

I am running the internal_communication mesh example provided with the esp-idf on three adafruit ESP-32 feathers. According to the serial output the devices can see each other as mesh AP's but the devices never actually connect to each other. Is there anything I need to add to this example code to g...
