Merger also seems to be working (cursor spinning, and merge statistics ~ok). However the > TapeServer doesn’t write anything to disk (just empty an file). > > A few observations; I only took ‘systematic’ notes after we had reduced the number of FEEs to 8, but it's > likely we were also facing the same problems before with a full system: > > + When enabling data transfer from NNAIDA modules (in Run Control page), it switches to the right mode for > all FEEs except for NNAIDA5. NNAIDA5 is the master FEE. The merger also doesn’t show any stats for NNAIDA5 > (but stats look ok for all other FEEs). The spectra for NNAIDA5 look ok, so the FEE is generating data. > > + A few times we observe the following behavior: DAQ running without trouble. We start Merger+TapeServer, > and when attempting some actions in RunControl (start-stop, or reset), we loose the ability to communicate > with a number of FEEs. These FEEs can not perform a ReSYNC, and the only way to get them back to life is > going through a power cycle. It seems like the TaperServer or Merger is somehow upsetting the FEEs or the > DAQ. We can still ‘ping’ all FEEs, even after the ‘connect failed’ message. > > Attached are a few screenshots, and the text in the terminals for Merger and TapeServer.
