ESP32 Forum

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?

Looks like an out-of-memory error of some kind.
