Re: [lwip-users] Connection abort due to max SYN retries reached
After looking at the changelog, I also guess it must be your test. What's changed there is that slowtmr checked for == max retries and I've changed it to >=. The old code had the assumption that nrtx was increased in the timer only, but in SYN_SENT, it is increased asynchronously as well.

(test by just repeating send http request) It's easy to get below debug message: tcp_slowtmr: max SYN retries reached Just a guess: could it be that your test is making so many connections so fast that you're cycling through all local port numbers and thus end up reusing them, while previous connections with those port numbers are still in TIME_WAIT state on the web server side at the time that the first SYN is sent for the new connection on the client side? It should be fairly easy to check this with netstat on the server side, if you have access to such a tool there of course. If that is indeed the case, behavior would definitely differ between 1.4.1 and 2.0.x due to patch #9039 and bug #50498, although it would then be a matter of perspective as to whether the issue is with lwIP or your test..
