Fatal exception 29 error

[Loucotolo]

Hello I'm using 2 esp8266, 1 as server mqtt using your "uMQTTBrokerSampleOOFull" example, and the other with the mqtt_pub.ino example,

I came across the following: when I first connect the client to the server everything works fine, but if for some reason the client restarts, the server gives me a Fatal exception 29 error (StoreProhibitedCause). I will put my code on both the server and the client and the respective log with the error. I hope someone can help me to find out where the error for this happened

Hello, I have the same problem with two wemos D1 mini boards. One as broker and the other as mqtt client. The fisrt conection is working OK, but when the client is reconected. (resetting the client board for example) the broker reconect it as other client but the previous conection is still active (I can see client_count is incremented by one) Probably the broker, for the same reason, is not disconnecting the former client and is connecting a second client with the same ID, and thats why is crussing The same happend with the pussubclient library loaded in the wemos client. I tried the broker library with other clients reconecting without any problem. I hope it helps a little to solve the problem.
