Folks, I find that people frequently have problems with dropped frames when running GigE cameras on Linux, particularly under heavy CPU loading.
In 2013 I posted a message to tech-talk (http://www.aps.anl.gov/epics/tech-talk/2013/msg02491.php)
about this problem. It contained a link from Tom Cobb to a Point Grey Knowledge Base article with a solution, which involves increasing some system values as follows: sudo sysctl -w net.core.rmem_max=1048576 net.core.rmem_default=1048576 I found today that the Point Grey link in that message no longer works. However, here is a new link that does work. http://www.ptgrey.com/KB/10016 Mark |
