Recently I have either been ABLE to log in to the Admin Panel or have not been able to---I know that sounds weird, here's what happens:
The times I cannot log in I get the following message under the log in area:
====
Warning: Unknown(): write failed: No space left on device (28) in Unknown on line 0
Warning: Unknown(): Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0
====
If I wait a little while and try again, I can log in. This is obvsiously concerning for all sorts of reasons. Any thoughts/ideas??
