Found all Merger Links background black - inactive. Nontheless the tapeservice was working, the data rate to disk was normal, and the file was being written and the histograms were being updated.

Decided to stop DAQ, stop Merger, restart merger. Links rest to green background - but no more writing to disk!

Killed Merger, killed Tape Service. Restarted.

Netvar read out at 3 - set to 1. When the Output of the Merger is enabled Netvar returns to 3. Tapeservice not writing to disk

Killed Merger, killed Tape Service. Restarted x3. Same behaviour.

Not working. No blocks being written.

With Tape Server status Stopped Ticked No storage, Unticked No storage -> Now writing blocks ?!

Tape Server Go. Writing to disk. Merger OK. Histograms updated, observables as normal (see next ELOG).

Lost runs 84-89 in the process.
