Stable – up to now
It looks fine up to nowL the system has been up and running continuously for 48 hours, without a glitch. The ususal peak on Monday just after midnight (processing last week’s logfiles) didn’t trouble it, nor does the occasional higher dem,and on resources – it seems that the last two days, the system has been quite busy between 14:30 and 16:30, acccording paaks in HyperSpy output:

The peaks also show up in the WASD graph over the last 72 hours (starting when the system was booted – the part before holds no data, of course):

Next is to contact the supplier for a replacement DIMM, for the one that seems to be bad.
