Hi, I'm using netconn API and running with FreeRTOS. When test my application with current lwip git tree. I recently found it's easy to get connection abort when I test connecting web server. (test by just repeating send http request)
It's easy to get below debug message: tcp_slowtmr: max SYN retries reached I tried increase TCP_SYNMAXRTX but it seems does not help. However, if I switch back to use lwIPv1.4.1 I never hit the "max SYN retries reached" issue. Is there any special setting needs to set in lwIPv2 to avoid such problem? Did I miss something when upgrade to lwIPv2?
