you looked at the source code? If so, can you point to any potential issues?** Have not dug into the camera server source yet. On some vehicles this works fine for hours at a time. On others, this issue pops up consistently. We have swapped cameras, cables, etc. We thought perhaps it was ripple or other issues to supply. It does seem to happen more frequently when extensions are used, as expected. Perhaps EMI and need for more custom/shorter cables? ## Reply by Moderator (ModalAI staff) · 2024-04-27 19:31:27 UTC @Steve-Turner Hi Steve, have you tried swapping cables and sensor modules? It seems most likely something is worn or loose. ## Reply by Steve Turner · 2024-04-30 20:51:48 UTC (in reply to Moderator) @Moderator we have tried swapping modules, cameras, and VOXL2(minis) Generally, it is exacerbated by the extension cables.
