Hi @fjpanag , Could you please confirm whether tcp_alloc uses the fall-back connection instance when the assert() triggered? https://github.com/apache/incubator-nuttx/blob/master/net/tcp/tcp_conn.c#L638-L704 (perhaps you need to add some debug logs to track the pointer of "conn"), I guess the issue you encounter maybe as blew: ``` 1. tcp_close ready and queue the lpwork to free the resources: net/tcp/tcp_close.c: tcp_close_eventhandler | ->work_queue (LPWORK priority 100) 2. High priority task( > 100) open socket and allocate the tcp_conn instance, no free connections and fall-back to active list to found out the close pending instance socket | ->tcp_alloc /* conn->crefs++ */(https://github.com/apache/incubator-nuttx/blob/master/net/tcp/tcp_conn.c#L638-L704) | ->connect 3. High priority task blocked on connect(), task yield to lpwork, tcp_close_work() | ->tcp_free() | ->assert() (conn->crefs > 0) ``` -- This is an automated message from the Apache Git Service.
