[AG-TECH] 'Yellow' flash in vic

The problem that I saw was an "orange" flash related to cpu loading
on a pig when using multiple Osprey video capture cards. I could cause
occasional flashes with a single Osprey card, but it took some serious cpu
slamming to cause it in that configuration. Multicast was not an issue.
The solution (read: kludge) for our case was a small software hack
that raised the relative cpu priority of the video capture processes under
the Ag 1.2 release.
I have not encountered the "yellow flash" multicast related problem
that other people have mentioned so I don't know if there is any relation
between the two phenomena.

Subject: [AG-TECH] 'Yellow' flash in vic
I've noticed recently that some of my machines (I thought it was only on
one that has a single 2.4GHz Xeon, but now I'm seeing it on a dual), that
there is sometimes a yellow flash that occurs on some of the cameras. I've
not done any tracking of type, graphics card, etc., but I'm wondering if
this is a known occurrence, and if there is any info as to whether it is
overloaded CPU, lack of memory, insufficient graphics card or none of the
above.
And if there's a FAQ that I can peruse - just whack me up-side the head
with it!
Thanks!!
