Fatal Error: PSIO_ERROR:

Fatal Error: PSIO_ERROR: 21 (File not opened)
Fatal Error: PSIO_ERROR: 6 (file is already open)
Fatal Error: PSIO_ERROR: 17 (Incorrect block start address)
Fatal Error: PSIO_ERROR: 18 (Incorrect block end address)

I often meet those errors when doing

polar = psi4.properties("cc2", molecule=geo, properties=['polarizability'])

I guess those are from some file errors?
What is the possible reasons that cause the error above?

Fatal Error: PSIO_ERROR: 21 (File not opened)
You need to open file 102 before you attempt this operation,
If you’re a user, contact developers immediately. This is a bug.
If you’re a developer, get yourself some coffee.

Yes, these are I/O errors, and they might be occurring due to your disk filling up. Without more information about the size of the calculation and your available disk space, however, it’s not possible to diagnose it.

Thank you for the comment. I see, available disl space is actually sufficient. calculation size is also not large …

Actually, a lot of unknown files are generated under /tmp/ something like

These behaviour did not apper in calculation with “MP2”
These behaviour apper in calc. with “CC2”
