Can you log in as root?
If so, please post something like:

df -k

Bring the system up in single user mode, and delete the contents of /tmp and then start looking for files to delete.
Try the following places.
/usr/adm/messages
/usr/adm/syslog
/usr/spool/lp/logs
/usr/spool/mail

When you have 3 or 4 mb of free space run:
cd /
du -a |sort -r -n >/tmp/list

use list to determine what files to delete next.

If it will not complete the boot to single user mode, boot from a diskette, and mount the root file system, then do the deletes.
#mount /dev/hd0root /mnt

unable to login
because time & again server giving same message

You should be able to get to single user mode. Enter the root password at the:
"Enter root password or type <ctrl>d to continue" prompt.
If not, then you will have to boot from an emergency boot floppy.
