Kite ticker websocket suddently crashes without error

# Assign the callbacks.
kws.on_ticks = on_ticks
kws.on_connect = on_connect
kws.on_close = on_close
kws.on_error = on_error
kws.on_reconnect = on_reconnect
kws.on_noreconnect = on_noreconnect
kws.on_order_update = on_order_update
# Infinite loop on the main thread. Nothing after this will run.
# You have to use the pre-defined callbacks to manage subscriptions.
logging.info("Starting  Kite-Ticker connect...")
kws.connect()
logging.info("Kite connect infinite loop exited for some reason")

I have been mining kite ticker data for 1 stock but my program all of a sudden closes without any error. The below command line starts my program in background and stores logs in a file.
python3 websocket.py > info.log 2>&1 &

I have even enabled kite ticker debug using kws = KiteTicker(apiKey, accessToken, debug=True), which prints ping ,pong logs.
I have also added logging messages in all the above call backs.

But....
1. My program exists (usually runs fine for 30 mins to 2 hrs before exiting), and no call backs (on_error, on _reconnect, on_noreconnect...) are called (no message printed)
2. I get the messages about web socket started and "Starting Kite-Ticker connect" which is printed just before kws.connect()
3. I dont see the log message "Kite connect infinite loop exited for some reason"


From these, I'm thinking that the kws.connect crashed, but there is no message. Was this issue faced by anyone, if yes, then what is the solution ?
