Subject: Dropped frames from GigE cameras on Linux

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.
