And the lwip is stuck, while other threads work well. I meant that httpd is
no longer responding to any request and also sntp is not able reach remote
server.
Both threads serving lwip, called lwipthread and tcpip_thread are in good
state and not overflooded.
Any ideas what can be the cause?
Thanks.
