I ran into the following problem:

What can cause such a segmentation fault?

hmm, how is your disk space?

10GB of free space should be enough, shouldn't it :-)

yeah, I just noticed this msg:

GMTS: Error: Time variable found, but values not found (tdimlen was 0)

Sounds like a disk error in the middle of the post-phase processing, so it explains the crash, although it is annoying that it happened. This code has been pretty reliable so I imagine it "burped" on a disk write.

It just happened again, same computer, same error message, but different work unit. And there is enough disk space available.

I have another computer running CPDN, who will finish phase 1 in a few weeks, so we will see whether the problem is computer related.
