Summary: LWIP assert "pbuf_free: p->ref > 0" and "tcpip_thread: Invalid message" reported Group: Savannah Administration Submitter: kuldeepp Submitted: Wed 28 Aug 2024 07:45:15 AM UTC Category: Savannah trackers - bugs, tasks, etc. Priority: 5 - Normal Severity: 3 - Normal Status: None Privacy: Public Assigned to: None Originator Email: Operating System: None Open/Closed: Open Discussion Lock: Any _______________________________________________________ Follow-up Comments: ------------------------------------------------------- Date: Wed 28 Aug 2024 07:45:15 AM UTC By: Kuldeep Siddheshwar Patil <kuldeepp> Currently, we are using lwip 2.2.0 version. We are runing basic ethernet features such as iperf, mqtt, long ping together to test endurance. But we observed that lwip assert is reported "pbuf_free: p->ref > 0" and "tcpip_thread: Invalid message". The current configuration we are using are below, PBUF_POOL_SIZE = 40 MEM_SIZE = 40 * 1024 LOCK_TCPIP_CORE() TCPIP core locking is enabled MEMP_OVERFLOW_CHECK = 0 LWIP_TCPIP_CORE_LOCKING_INPUT =0 TCPIP_MBOX_SIZE = 32 When I investigated I found that, (netif->input( p, netif) != ERR_OK) this condition is satisfied. but don't know the root cause of that. Request you to please provide your input and if required more information for debug let me know. Thanks in advance. _______________________________________________________ Reply to this item at: <https://savannah.nongnu.org/support/?111112> _______________________________________________ Message sent via Savannah https://savannah.nongnu.org/
