Got it to work - I think.

13*2^905-1 produced filtering message "matrix not dense enough, retrying" a few times, finally building a matrix of density 40 (target density was set to 140). After ~70 hrs of LA, only the trivial dependencies were recovered.

Restarting postprocessing with filter_maxrels set to 310M.

Next time, is "matrix not dense enough, retrying" the sort of nearly-fatal message that should incite me to restart filtering with fewer relations?

I saw that message once but didn't think much about it because it eventually completed. But it was a 10 day solve.

Strangely enough, that message seems to appear in two different situations. One is that there aren't enough relations, and the other is that there are too many. In practice I've only seen it in the latter situation.

In this case, the number was way oversieved. For a 31-bit job, 250M should have been plenty. Some extra can produce a smaller matrix, but 350M is firmly in the territory where one sees this problem. I would probably have just started with maxrels set to 300M.
