BT_OSI: osi_alarm_new alarm_cbs exhausted

[mm_1993]

Hi

I'm Using esp32 c3 - idf 4.3 -> ble mesh example

in menu config -> component config -> esp ble mesh support -> support for ble mesh provisioner ->
* Maximum number of PB-ADV running at the same time by Provisioner
* Maximum number of PB-GATT running at the same time by Provisioner

when I Change the Number of provisioner from 3 to 5 provisioner an error occur :
BLE_MESH: Alarm not created
BT_OSI: osi_alarm_new alarm_cbs exhausted

and it's another Error again :

I only know when this happens that I add new element to my code:

static esp_ble_mesh_elem_t allMeshElements[] = {
ESP_BLE_MESH_ELEMENT(0, rootModels, vendorModels),
ESP_BLE_MESH_ELEMENT(0, channel_2_dimmer, ESP_BLE_MESH_MODEL_NONE), // element 2
};

why these errors happen ? there is no document ???

Hi, Am also facing same issue.
Did you guys get any solution?

What i need to change if i am looking to do a large number devices provision using ESP32 provisioner.

Well if someone is going to have the same issue after the next few years, then they should increase CONFIG_BT_ALARM_MAX_NUM to like 80 in sdkconfig and rebuild the project. There is a thread on stackoverflow where it was said as a solution and it really works.
Although there was another problem with the example when I run it. I was using an example from IDF 5.2.2 and there ESP_BLE_MESH_KEY_UNUSED and ESP_BLE_MESH_KEY_UNUSED were defined differently. I had to manually fix this. But in IDF 5.3.1 it seems to be ok here:
