News, Tango trouble after reboot, P21: changing the harmonic of the undulator, open Lambda HDF files with silx

• Tango trouble after reboot, P01: mysql did not start properly, after a tango start everything is ok.

  The general solution to this issue is known: update all hosts to 4.19.0. We found this too late for a general update today. However, BL scientists may ask for it. Takes a call to MF and about 20 minutes.

• P65, Undulator: changing the harmonic changes the limits, ongoing.

• P08, open Lambda HDF files with silx: Lambda Tango server appends frames to a file. This creates a conflict, if silx opens the file.

  Options: the lambda TS keeps the file open, not so good

  LaVue can now dump images to a temporary HDF file which can be opened by some application. Florian is looking at it.

• P23, Amptek stops, if too many counts: test time needed

• P01, bug in 4-circle version of the hkl lib. HG to describe the error.

• SardanaMonitor slows down (P06): tests

• P23, SardanaMotorMenu freezes: ongoing

• P64: re-consider the calibration procedure of the MC: perp and par motors should not be calibrated but moved. WC to propose a procedure, then approve by P3C.
