In no particular order 1) Options variables unexpectedly changing or becoming unset/undefined - see https://elog.ph.ed.ac.uk/DESPEC/205 Is this why *.L, *.H and Rate spectra are undefined in some FEE64s? 2) Merger 'Bad Timestamp' error reports - e.g. see https://elog.ph.ed.ac.uk/DESPEC/203 Meaning of report? Significance/impact? 3) Large numbers of PAUSE/RESUME for some (but not all) FEE64s - see e.g. https://elog.ph.ed.ac.uk/DESPEC/203 Significance/impact? -- NH to add 4) Slow but non-zero increase of White Rabbit errors (mostly timestamp but much rarer ASIC errors) We know the White Rabbit network in general is reliable but could we see interruption to the 200 MHz clock or 10 kHz timestamp when FATIMA DAQ is busy/restarting Wasn't uniform over all FEEs implying a more local source though? -- OH to add 5) The dropping of links between FEEs and the MERGER. Quite often these were correlated with the 'Bad Timestamp' error messages and also the WR errors ---- PJCS to add 6) The addition of the NIM clock-divider to allow better ASIC clock synchronisation.
