Connection is already closed. - data: None -- OrderBook Socket Closed! --

[sandbohx]

After running the orderbook.py script for a few hours, I always run into this problem: Connection is already closed. - data: None

-- OrderBook Socket Closed! --

The script still runs - it doesn't exit but The connection is auto closed and goes into and endless looped sleep state. Anyone else experiencing this and know what the problem is? Thanks.

I'm experiencing it. I presume it's a result of some interruption in the TCP connection, either at GDAX's end or somewhere in the network in between. However I haven't spent time to investigate with any depth.

I'm handling it, at least temporarily, by setting a boolean (self.connected) to True in on_open, and False in on_close. And then in my main thread checking that occasionally and when I see that it is false I throw away my websocket client and create a new one to trigger a new connection. The WebsocketClient has a somewhat similar boolean (self.stop). Oh, and now that I look at the code again it should be flipped by an error like this as long as you haven't overridden the default on_error function. So you could probably poll for the state of that variable instead.

hi jheiss, thanks for your response. I am new to python and I'm not sure how to get the status of a variable in another module. What I noticed is that after I get the error, my try statement is still putting the script to sleep. So presumably, I can place the code which checks the state of self.stop here. Question is how do i grab the self.stop state in order_book.py from websocket_client.py? Thanks!

My attempt below:

order_book = OrderBookConsole()
order_book.start()
try:
    while True:

>             while self.stop:
> 				order_book.close()
> 				order_book = OrderBookConsole()
> 				order_book.start()

        print("sleeping")
        time.sleep(10)

Here's roughly what I'm doing:

while True:
    order_book = OrderBookConsole()
    order_book.start()
    while not order_book.stop:
        print("sleeping")
        time.sleep(10)
    order_book.close()

I'm glad I'm not the only one seeing this message. It crashes my script within a few hours every time. I have noticed that a few of those times GDAX had posted a temporary maintenance period, not sure how related that is. Is this something that I should be handling in my script?
