configuration for U2

[winspiral]

is this configuration ok?

"api-mcast-port" : "4028",
"api-port" : "4028",
"expiry" : "120",
"bitmainbeeper" : true,
"bitmaintempoverctrl" : true,
"hotplug" : "5",
"log" : "5",
"no-pool-disable" : true,
"queue" : "1",
"scan-time" : "60",
"shares" : "0",
"kernel-path" : "/usr/local/bin"

Sometimes my U2 works perfectly and sometimes not.

Now it does not work.

And now it does work perfectly.
Is here someone who has the same problems with an antminer U2...?

I have tested my U2 with 2 different pools
if it works with one it works with both.

if all works perfectly the green led goes on and off so long it works.

It happened that the green les stayed on...but no mining then...
what does this mean?
