[BUG] connectivity issue

[LuoQuestionmark]

Describe the bug I am recently playing with an OAK wide camera to do some object detection using the Depthai C++ libraries. There was desynchronization between the depth frame generated from camera and the captured RGB frame. So I tried to tune down the system with a 24 fps capture rate and isp 3a rate of 12 fps. However, while running the new version of program, the system seems to cease function after a while. The most recent test worked for 45 minutes before sending the following message:

[19443010D1B91F1300] [1.1] [3657.373] [system] [critical] Fatal error. Please report to developers. Log: 'pool' '180'

As it suggested, I am hereby reporting the error.

Minimal Reproducible Example

Due to the complexity of the multi-threading program that I am running, it is hard to write a short reproducible example. I will try to write one later.

Expected behavior

Capture program ceases to function, while the attempt of reestablish connection with a try-catch clause fails as well.
