Original HTTPD implementation of Suga koubou is great but has some bug inside unfortunately. The most critical bug was accessing buffer with the index of out of range like following.
problematic code
char buf[256]; n = httpd->_state[id].client->receive(buf, sizeof(buf)); buf[n] =0;
With above code, it could set buf[256] = 0 when more that 255 data is received. Setting buf[256] causes some other area of memory is corrupted so that system can be predictive status since than.
bug fixed code
n = httpd->_state[id].client->receive(buf, sizeof(buf)-1); buf[n] =0;
