Greg, Tobias, Christopher,
Thanks for all of your help. I've downgraded back to 1.1 now and the
system is back to normal functioning. All of your answers, however, have
helped me greater understand this mountain known as Matterhorn. An update to
1.2 is in the future, though I must say it would be nice if there was a big red
button on the server and each capture agent that said "Update" and did it all
for you, preserving your everything.
I have what I hope is to be my last question for a while: The whole reason I
tried to upgrade to 1.2 was because the core server was crashing because 4
agents recording 4 back to back classes each were all pushing data to it. In
order to beef up the hardware I took two of our rack mount computers apart and
combined them. I now have 4 cores, 8 gigs of ram, and 2 terabytes of HD to
use. My question is...if this configuration still crashes under the load is
there a way to defer processing until all classes are over for the day? If
there is please tell me how to accomplish this.
Thank you all again,
Nathan
