As you can see in the attached screen shot almost 2/3 of the data is
missing<br>
looks like only every 3rd package arrives.<br>

If you only saw part of the data, then that is probably the
issue that is mentioned in that knowledge base article, where
NI Linux isn't respecting the EPICS array size. Which ...

Windows or NI Linux. The current controller is in that overlap

is EOL).</div>

<div style="direction:ltr"><span style="font-size:11pt">Hi
Brian,<br>
<br>
I guess I screwed up the PXI again. I saw on Friday that it
was running<br>
and producing<br>
data however the data was "corrupted" and only part of the
data was in<br>
the root file.<br>
so I restarted the PXI ioc but that did not help so I
rebooted the PXI<br>
and of course that<br>
did not work either and when I rebooted it the second time
it did not<br>
come back.<br>
<br>
I think this may be a similar problem we had in the past
that the PXI<br>
does not get<br>
its IP address?<br>
<br>
I am going over the to the hall now to see what happens when
I reboot it<br>
right there.<br>
<br>
cheers,<br>
Beni<br>
