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.

Follow-up Comment #1, sr #12 (group administration):

This was mistakenly posted to site administration instead of to the lwip
project.  Forwarding.

You've reached the support tracker of Savannah, the software forge; however,
your request is about some software, and unfortunately, it isn't clear what
software package you are reporting about.  So I can only suggest that you find
the right communications channel.
