Well / can be full...but still have enough room for root user to cleanup before disaster...
e.g. normally with HFS you used to have 10% reserved ( full for all users except root...).
With vxfs full at 95% you would be unable to extend the file system for lack of space for reorg...
Now I doubt it being because of wtmp or wtmpx for you would most certainly be unable to connect if you were not root... and you would have system logs warning you about the near coming issue, all I can think of is look for a specific file especially if someone used tar to backup/archive and most common issue is someone misspelling the tape device path, I had long ago a very important server crash because of that... I was lucky finding in /dev a /dev/tape when the system had 2 devices: a spooltape device and a DAT device and the path should have been something starting by /dev/rmt/XXXX
/dev is not very big type

Code:

 du -sk /dev

if its more than 60MB then the culprit is hidden somewhere there... if /var is full then some cleaning is necessary to be able to use vi for a start (on HP anyway...) all the system logs need to be able to write!
Your system look like a solaris is it so?

wtmpx

utmpx(4)							   File Formats 							  utmpx(4)

NAME

       utmpx, wtmpx - utmpx and wtmpx database entry formats

SYNOPSIS

       #include <utmpx.h>
       /var/adm/utmpx
       /var/adm/wtmpx

DESCRIPTION

       The utmpx and wtmpx files are extended database files that have superseded the obsolete utmp and wtmp database files.

       The  utmpx database contains user access and accounting information for commands such as who(1), write(1), and login(1). The wtmpx database
       contains the history of user access and accounting information for the  utmpx database.

USAGE

       Applications should not access these databases directly, but should use the functions described on the getutxent(3C) manual page to  inter-
       act with the utmpx and wtmpx databases to ensure that they are maintained consistently.

FILES

       /var/adm/utmpx	       user access and adminstration information

       /var/adm/wtmpx	       history of user access and adminstrative information

SEE ALSO

       getutxent(3C), wait(3C)wait.h(3HEAD)
