[BUG] bug with log "Please report to developers."

[LuoQuestionmark]

Describe the bug

While trying to connect with two PoE cameras, the following error occurs, and the connection is broken.

[184430105145A20F00] [169.254.1.11] [6079.212] [system] [critical] Fatal error. Please report to developers. Log: 'pool' '180'

Another suspicious error is

[1844301091838E0F00] [169.254.1.12] [1701967503.847] [host] [warning] Monitor thread (device: 1844301091838E0F00 [169.254.1.12]) - ping was missed, closing the device connection

which is yet another problem.

Minimal Reproducible Example

Have not written one yet.

Expected behavior

Lost connection with the reporting camera.

Additional context

I have reported the same error here with no response. The bug seems to happen less frequently if:

• connection via PoE rather than via USB ;
• less image processing on each iteration ;
• connection with only one, not two cameras ;
• program running with 2.23 version of library instead of 2.22.

Log

The following log is from my program. Each record with a timestamp ahead is generated by my program; others are from the library.

Hi @LuoQuestionmark, sorry for the issue. Please provide an MRE so that I can reproduce and fix the bug.

[LuoQuestionmark]

@asahtik
One such example is currently being written; since I need to remove a lot from my existing code while making sure that the bug can be reproduced, it can take a several day before it is finished.

update 14 Dec:
I am still trying. It is the first time that I try to recreate the error whereas it just does not happen.

@asahtik

Sorry for being late, I have been trying to reproduce the bug with a simpler program instead of the project I am working on, with multiple header files, classes, etc.. To this point I have written a program even more complex than the original program I had making the bug; and the program still cannot reproduce the bug. Therefore I decide to stop for now, if I happen to make it happen again I will return with updates.
