Hi, I am using LwIP 2.0.3 with FreeRTOS version 10. There is separate 'ethernetif_input' task which handles Ethernet. We are running httpd.c server over raw api as provided by LwIP stack. The priority of Ethernet task is 2nd most among all threads. It is working fine but randomly somehow 'tcp_active_pcbs' got corrupted and becomes circular linked list of 'pcb'. The code got stuck in 'tcp_in.c' under loop 'for (pcb = tcp_active_pcbs; pcb != NULL; pcb = pcb->next) '. This happens most of time when server(controller) is running and if the controller get restart. We are starting 'ethernetif_input' task only after all the initialization takes place.
I tried debugging hard but i don't see anything. That is why I am writing for the help. Thanks in advance. -- Sent from: http://lwip.100.n7.nabble.com/lwip-users-f3.html _______________________________________________ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users
