Hi Catherine,

Thank you for the reminder.

I don't recall what I was thinking back then (big surprise), but there are some notable points from that mmms output.

There are 4 matrix columns that show min = max = stdev = 0, and 2 that are very close to that. What do these 6 columns look like?
I suppose 43, 44, 49 and 50 are all zero. But 42 and 48 are surely close to that. Any all-zero columns will lead to warnings.

col 42: min = -0.0000, mean = 0.0000, max = 0.0001, stdev = 0.0000
col 43: min = -0.0000, mean = -0.0000, max = 0.0000, stdev = 0.0000
col 44: min = -0.0000, mean = -0.0000, max = 0.0000, stdev = 0.0000
col 48: min = -0.0000, mean = 0.0000, max = 0.0001, stdev = 0.0000
col 49: min = -0.0000, mean = 0.0000, max = 0.0000, stdev = 0.0000
col 50: min = -0.0000, mean = 0.0000, max = 0.0000, stdev = 0.0000

There are also many columns that have identical mmms results, though that does not imply they are the same. But moving the "col xxx:" text to the end of the line and sorting, we see these all have the same output (for example, there are other sets as well):

min = 0.0000, mean = 0.0010, max = 1.0000, stdev = 0.0320 col 164:
min = 0.0000, mean = 0.0010, max = 1.0000, stdev = 0.0320 col 165:
min = 0.0000, mean = 0.0010, max = 1.0000, stdev = 0.0320 col 166:
min = 0.0000, mean = 0.0010, max = 1.0000, stdev = 0.0320 col 167:
min = 0.0000, mean = 0.0010, max = 1.0000, stdev = 0.0320 col 168:
min = 0.0000, mean = 0.0010, max = 1.0000, stdev = 0.0320 col 169:
min = 0.0000, mean = 0.0010, max = 1.0000, stdev = 0.0320 col 170:
min = 0.0000, mean = 0.0010, max = 1.0000, stdev = 0.0320 col 171:
min = 0.0000, mean = 0.0010, max = 1.0000, stdev = 0.0320 col 172:
min = 0.0000, mean = 0.0010, max = 1.0000, stdev = 0.0320 col 173:
min = 0.0000, mean = 0.0010, max = 1.0000, stdev = 0.0320 col 174:
min = 0.0000, mean = 0.0010, max = 1.0000, stdev = 0.0320 col 175:
min = 0.0000, mean = 0.0010, max = 1.0000, stdev = 0.0320 col 176:
min = 0.0000, mean = 0.0010, max = 1.0000, stdev = 0.0320 col 177:
min = 0.0000, mean = 0.0010, max = 1.0000, stdev = 0.0320 col 178:
min = 0.0000, mean = 0.0010, max = 1.0000, stdev = 0.0320 col 179:
min = 0.0000, mean = 0.0010, max = 1.0000, stdev = 0.0320 col 180:
min = 0.0000, mean = 0.0010, max = 1.0000, stdev = 0.0320 col 181:
min = 0.0000, mean = 0.0010, max = 1.0000, stdev = 0.0320 col 182:
min = 0.0000, mean = 0.0010, max = 1.0000, stdev = 0.0320 col 183:

So start by looking at how these were created, and see if there is anything peculiar in those timing files. Please feel free to post timing files that you are concerned about.
