Description

Jon Paley reports:

I'm trying to run integtest.  When I get to the point of clicking "BeginRun" in the RC, the data logger crashes in a way I haven't seen before.  The error message reported:

ERROR / DLRCC

novatest01.fnal.gov (131.225.80.170)
NovaDataLoggerapp (30587)
DataLogger / DataLogger / MF-online
Existing Shared Memory segment has a size less than the requested minimum (Requested: 20971520, Actual: 1024 )

=======================================
Background: this has been a problem in the past on NDOS. Is it fixed by having startSystem take care of the segment? How do we fix it for integtest? (And how have others avoided it?)
