Solaris Common Messages and Troubleshooting Guide

No utmpx entry

Cause

During login, file system full errors are seen and the login fails with the message No utmpx entry.

This error is caused by a full file system. The system has no space to write its utmpx (login information) entry.

Action

To correct this condition the system must be booted into single user mode. Then clear (do not delete) these files: /var/adm/utmp and /var/adm/utmpx. This can be done by typing: 


#cat /dev/null > /var/adm/utmp
#cat /dev/null > /var/adm/utmpx
These commands zero-out the files but keep them with the correct permissions.

In some cases, after clearing these files, the /var file system might still be full. In this case type: 


du -askd /var |sort -nr |more
This command gives you a listing of the files from largest to smallest in the /var file system. To create space you can zero these files: /var/cron/log, /var/spool/lp/logs, and /var/adm/messages. You can also check /.wastebasket for large files to delete.
