signalR constant growth of system objects

[Nivonn]

Hi.
I've created a client server demo where the server pushes data to the client every 5 seconds.
code
When I take memory snapshots (chrome->F12->memory->heap snapshot) every couple of minutes, I see constant growth of system objects (the purple segment on the pie chart).
It seems that this issue causes the browser to fail over a short period of time.
You can watch the evolution of the purple segment from snip1 to snip5 in the attached files.
Can you please advise ?
Thx
