BLE GATT Client freezes after 3 Connections

[Intrpt]

Hi guys,

i'm trying to get a BLE GATT Client running which has to connect multiple GATT Servers (up to 30). I'm using Arduino-ESPIDF with PlatformIO. I changed my sdkconfig.defaults to: (For testing I changed it to 9 devices)

# Override some defaults to enable Arduino framework
CONFIG_ENABLE_ARDUINO_DEPENDS=y
CONFIG_AUTOSTART_ARDUINO=y
CONFIG_ARDUINO_RUN_CORE1=y
CONFIG_ARDUINO_RUNNING_CORE=1
CONFIG_ARDUINO_EVENT_RUN_CORE1=y
CONFIG_ARDUINO_EVENT_RUNNING_CORE=1
CONFIG_ARDUINO_UDP_RUN_CORE1=y
CONFIG_ARDUINO_UDP_RUNNING_CORE=1
CONFIG_DISABLE_HAL_LOCKS=y
CONFIG_ARDUHAL_LOG_DEFAULT_LEVEL_ERROR=y
CONFIG_ARDUHAL_LOG_DEFAULT_LEVEL=1
CONFIG_ARDUHAL_PARTITION_SCHEME_DEFAULT=y
CONFIG_ARDUHAL_PARTITION_SCHEME="default"
CONFIG_AUTOCONNECT_WIFI=n
CONFIG_ARDUINO_SELECTIVE_WiFi=y
CONFIG_MBEDTLS_PSK_MODES=y
CONFIG_MBEDTLS_KEY_EXCHANGE_PSK=y

# Example configs
CONFIG_BT_ENABLED=y
CONFIG_BTDM_CTRL_MODE_BLE_ONLY=y
CONFIG_BTDM_CTRL_MODE_BR_EDR_ONLY=n
CONFIG_BTDM_CTRL_MODE_BTDM=n
CONFIG_BTDM_CTRL_BLE_MAX_CONN=9

My Code is compiling, running without errors. But it is freezing after 3 Connections. I figured out it is in a deadlock while waiting for m_semaphoreOpenEvt.wait("connect"); in BLEClient.cpp After 2-3 minutes, this hapens:

Firrst I thougt it is a memory shortage, but it memory seems fine: 1 Connction: ␛[0;33mW (1650) TAG: 28: - RAM left 172876␛[0m 2 Connection: ␛[0;33mW (4390) TAG: 28: - RAM left 166940␛[0m 3 Connection: ␛[0;33mW (5140) TAG: 28: - RAM left 162492␛[0m

Any ideas? I'm stuck right now.
