mxRun() returns without error, model claims to have not been run...

Several core users report models (typically running for many hours) returning as if the run was successful, but the returned model is marked as never run, contains no output.

I think all cases involve ordinal/binary data or joint ordinal.

CSOLNP is known to have this behavior, May affect NPSOL as well: need to check and update this bug report

Happens with 1 core as well as several.

Mike suspects optimiser finds an -Inf log likelihood and quit.

We should at least return a code red and the parameters from the lowest -2ll (constraint-satisfying) run rather than confuse the user by claiming they never tried to run the model ( which is what summary says

Better yet of course to be able to run realistic joint ordinal models without error...

Does anyone have a script that produces this behavior? I don't doubt that it exists (existed). There's just nothing I can do without more concrete evidence.

So long ago that no one can verify this issue's existence. Maybe fixed, maybe not. We'll keep an eye out for it, but close it in the meantime.
