Thank you for reply.  
The size is - #define MQTT\_COMMAND\_CONTEXTS\_POOL\_SIZE ( 10U )  
I used the MQTTagent example code as a basis. As I understand it, there is a problem with determining the state. As I wrote[FORUM POST](https://forums.freertos.org/t/global-varaiable-of-mqtt-broker-state/21569/11) earlier, the MQTT\_CheckConnectStatus(pMQTTContext ) function does not work correctly if the link to the Internet remains, but it is the broker’s server that is disconnected. The problem does not occur if you physically pull out the ethernet cable, then the cycle stops
