I have an ultra 5 box running SunOS 5.6, since a reboot last week the following error message has appeared on the servers screen resulting in no one being able to login to the box direct: -
INT: Command is respawning too rapidly. check for errors.
id: co "/usr/lib/saf/ttymon -g -h -p" uname -n' console -m idterm, ttcompat"
This is just test box and not a major problem as users can still login to the box via ssh using putty and f-secure.
Check your /etc/inittab - either someone added something or changed something messing up the entry giving the error OR someone or something has messed up the executable. Look at the inittab first....
The entry you show on a Solaris 2.6 - from one of the 2.6 servers at my site (it's the last entry in /etc/inittab - when you vi the file, check the line with : l - look for white space at the end of the line which could mess it up):
