Could you do the following:
1) enable coredumps
2) set in nginx.conf:
3) reconfigure nginx, if there are open connections, then nginx creates
coredump on exit
4) look in log for alerts: open socket #... left in connection NN
5) run "gdb /path/to/nginx /path/to/core", then
p ((ngx_connection_t *) ngx_cycle->connections[NN]->data)->uri
p ((ngx_connection_t *) ngx_cycle->connections[NN]->data)->main->count
do not forget to set NN from log message.
