Unhandled Exception: Not enough quota is available to process this command

[swcooke]

I have built a custom Indicator that continually throws this error:
Unhandled Exception: Not enough quota is available to process this command

Here is the section from the trace file that starts at when I loaded the Indicator (red bold indicates issues, I think):

I am continuing to debug and will add more here as I learn more but if you have any ideas, please let me know.

Hello swcooke,

From the given details I couldn't really say what may cause that. The error you are seeing is a general windows error. You can search online for some details on general causes or solutions however without knowing what code you used it would be difficulty to say why that may be happening. After you have further isolated the issue, if you have further questions on the code involved we can go over that.

I look forward to being of further assistance.
