Hi Ashton
it seems your MWCS computation took a looooooong time and the MySQL
connection was killed during that time. Can you confirm ?

I get a strange crash part way through my MWCS step (see below), and
compute_MWCS is not finishing. E.g. I have 5 frequency bands, but for bands
2-4 only 1 of 10 station pair MWCS's get calculated, even though all the
data is there in the stacks. I have tried rerunning comute_mwcs by changing
the flag back to 'T' for the station pairs where mwcs did not get
calculated, but it still crashes. This crash is repeatable.
Any thoughts?
(p.s. I also initially tried remaking the stacks, but it crashed at the
same point. The data looks good in the stacks)
