We have two GigE cameras connected on separate NICs.\r\n\r\nIs there a reason that Threads are preferred? Is there an issue `fork`-ing the Vimba singleton in `Process` objects that could be causing an issue? The default behavior in creating `Process` objects on Linux is `fork` rather than `spawn`, so it is possible that using `spawn` does not create a problem for the Vimba singleton?","author":{"url":"https://github.com/mprat","@type":"Person","name":"mprat"},"datePublished":"2023-09-29T15:04:29.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/170/VimbaPython/issues/170"}
