## ESP32 crashes when listening_message_reliably

- Hardware description: ESP32 serially linked to a nRF5340DK (using UART1 on pins 19/18 as TX/RX)
- RTOS: FreeRTOS
- Installation type: micro_ros_espidf_component, ESP IDF v4.4
- Version or commit hash: humble

#### Steps to reproduce the issue
My project consist on controlling a BT Mesh provisioner via ROS, and transmitting sensors data from the Mesh network to ROS.
The ESP32 serves as a message bridge between the provisioner and ROS.
For that I've got 4 threads running :
- the uROS thread (priority 5, stack 16000 bytes) with 2 subs and 2 pubs
- an "uart_phy" thread (priority 6, stack 4096 bytes) which job is to read data from UART1 and sends it to uart_mac_rx with a message queue
- 2 "uart_mac_rx" and "uart_mac_tx" threads (priority 6, stack 4096 bytes). uart_mac_rx gets data from uart_phy and publishes message to ROS. uart_mac_tx receives messages from the subscribers callbacks and transmits data to UART1

The nRF5340 scans for unprovisioned ("unconnected") mesh nodes, and sends the UUIDs to the ESP32 via serial.
So the ESP32 receives a 16 bytes UUID from UART, the uart_phy sends this UUID to uart_mac_rx through a message queue.
uart_mac_rx wakes up because something is in the queue, sees that it is an UUID, and publish it with my "unprov_pub".
The ROS message is the following :
ble2ros_interfaces/msg/Beacon.msg
```
# Represent an unprovisioned beacon from BT Mesh
uint8[16] uuid
```

#### Expected behavior
UUIDs are sent to ROS without error

#### Actual behavior
Sometimes, mostly when the ESP32 receives a lot of UUID's to transmit to ROS, i got the following error :
`assert failed: pbuf_free IDF/components/lwip/lwip/src/core/pbuf.c:757 (pbuf_free: p->ref > 0)`
OR
`assert failed: tlsf_free heap_tlsf.c:872 (!block_is_free(block) && "block already marked as free")`

but mostly the pbuf_free assert failed.
The most frequent stack backtrace is the following :
```
assert failed: pbuf_free IDF/components/lwip/lwip/src/core/pbuf.c:757 (pbuf_free: p->ref > 0)

#### Additional information
I also had other configuration with at most 4 pubs and 4 subs, and this problem can occur with any publisher.
I went back to 2 pubs and 2 subs to get back to the basic uROS config (also resetted the max pub/sub in colcon.meta)

I looked if the heap became corrupted at some point, but it was always clean.

When disabling asserts, it stills crash with Guru meditation error: Core 0 panic'ed

I tried lowering priorities, (12 for UART, 11 for uROS), switching priorities (4 for UART, 5 for uROS), still got the same problem.

Looked over the internet for solutions, looked in this repo's issues, found nothing...

Looked if I had memory leaks, but found none

Commencez par les points d’entrée de la backtrace uxr_read_udp_data_platform, recv_udp_msg et listen_message_reliably, puis reproduisez l’échec avec la configuration ESP-IDF 4.4 sous un trafic UUID élevé. Comparez les échecs de pbuf_free et tlsf_free tout en vérifiant la configuration UART, task et publisher décrite. Le travail est terminé lorsque la cause du crash est isolée et que l’issue dispose d’un fix ou d’un workaround vérifié.
