Heap memory problem when wifi is cut off of internet

[shrynshjn]

I am using socket.io client to connect to my server using websockets. It works fine as long as the internet connection is there, but if i disable the internet keeping the wifi on It starts consuming heap, and also each websocket loop takes more time. I am not sure if its an issue with the library or a core esp8266 issue.

Time and heap before websocket run: 1120862, 38680 Time and heap after websocket run: 1126359, 38680 Time and heap before wifi run: 1126360, 38680 Time and heap after wifi run: 1126360, 38680 Time and heap before websocket run: 1126361, 38680 Time and heap after websocket run: 1136584, 38680 Time and heap before wifi run: 1136584, 38680 Time and heap after wifi run: 1136584, 38680 Time and heap before websocket run: 1136586, 38680 Time and heap after websocket run: 1142083, 38680

heap decrease and time increase happens at different times, I did confirm that heap decreases when I make a call to websocket.loop() inside my code. As you can see the time difference is about 6s in the iteration I copied here, it increases with time. using arduinoWebSockets 2.3.1 esp8266Core 2.5.0

The websocket client is also not diconnecting for a long time, even though the internet connection is closed and its only connected to a router. Interestingly this doesnt happen if a socket connection was never formed, or if the device router is shut down. Any guidance to how to solve this heap loss problem will be appreciated.
