I'm using lwIP 1.3.0, with an http-server like application (using as base the raw mode httpd in contrib).
When I have many connections to server, i.e. repetitively reloading a page, I quickly run into memory errors; enabling debug, and inspecting MEM TCP_PCB in stats, I find that all the TCP PCBs are in use, while all the connections have been closed properly -- inspecting them with WireShark. It needs some seconds (up to around ten), before the PCBs start being freed, and I have again sufficient PCBs for new connections -- I'm #defin-ing MEMP_NUM_TCP_PCB to 32 If I enable TCP_DEBUG I see the message "tcp_slowtmr: no active pcbs", even when stats_display() shows 100% of TCP PCBs used. What affects the time/mode to totally release the PCBs for a new task?
