What version of phenix do you have (phenix.version)?

Which phenix installer tar file did you use?

Did that same version work before?

Are you running automatic OS updates?

Do you have a 32-bit or 64-bit OS (uname -m)?

Yes, it is almost certainly a software problem, but what exactly is
difficult to know.

Could you try installing from sources?
This is not guaranteed to help, and you'll get slower solve and resolve
(gfortran optimizes very poorly), but it would be another data point 
for us.
To get the sources:
  https://www.phenix-online.org/download/phenix/nightly/?version=1.4-129&show_source=1
Replace the version number with the one you have already.
You will need the password again (which has just changed; you probably have
to re-request).
Don't forget to add --nproc=8 or similar to the ./install command, to
speed up the installation.
