[Halld-online] gluon crashes

[David Lawrence]

Hi Onliners,

  This morning we continued large scale DAQ system testing and development. We managed to get a system that
crashes a DAQ node within minutes. The configuration used separate nodes for each of the Data Concentrators,
Secondary Event Builders, and Event Recorder. There were approx. 28 ROCs involved. We have identified a
possible culprit (10Gbit ethernet port on the dual port card) and will test this on Thursday. Part of this testing
will require that we reconfigure the dual port cards and built-in NIC on the following machines:

gluon46
gluon47
gluon48

Dave Abbott will be doing this today and tomorrow. Please use another machine for any operations in the
meantime since these will be in flux for the next two days.

I also have a test running on gluon106 that may cause a crash there so you might want to avoid that one as well.

Regards,
-David
