Fatal crash: adding specific count to semaphore cause to exceed maximum count

[J_o_s]

Hello!

I got an unhandled exception with NinjaTrader just seconds after connecting a data feed:

(see attached image)

The full error message is:

"Unhandled exception: Adding the specified count to the semaphore would cause it to exceed its maximum count."

I searched Google for this NinjaTrader error, but didn't find any. (Apologies if the solution is already documented somewhere else.)

(Using NinjaTrader 8.0.21.1 64-bit).

Thanks in advance!

Edit: I now see that I made this topic in the wrong NinjaTrader 7 forum. How can I move it to the proper NinjaTrader 8 forum?

Hello J_o_s,

Close all open workspaces and see if the behavior can be reproduced in a new workspace with a new chart with no indicators applied.
Below is a link to a forum post with steps.

Give this a few tries.

This will let us know if its something in the workspace or something with the platform.
