It constantly check if connection to server is alive. If not then reconnect and if this das not help resets ESP.

It is gpio16, not 18. And you're right, there is no rst pin on the esp-03. But you could pull ch_pd to ground for a few ms to trigger a hard reset...

I have also been using CH_PD as reset but on the ESP-03, the little pad just right of the VCC pin is actually connected to the reset pin on the ESP8266. I soldered a wire to it. But so far, I haven't found any difference in using the reset pin or CH_PD
