Thanks. From the DESPEC elog.gsi.de/despec/Implantation+Stack/18

"We have made a trigger from the BGO logic and OR64 of the fast discriminator from AIDA. This was sent as a trigger to the bPlast Exploder.

This did not work as the FEE64s of AIDA are running into high dead-time and a result are dropping data. This is a problem for the ucesb unpacker as it will quite working if one of the subsystem stops sending data. (@Nic is this correct?)

This is indeed what I see as whenever we try to run FAIRROOT the tree builder exits immediately."
