4.0.3 problems

[Abdi M. Oday]

I recently upgraded a sun 4/110 to OS 4.0.3  (previously running 4.0.1)
The upgrade went smoothly, but The following messages keep popping up on
the console:

	 vmunix: dnlc_purge1: no entries to purge
	 vmunix:       inode: tabel is full

sometimes the following messages will appear between the above two:

	syslogd:   /etc/utmp: File table overflow

Does anyone know what is causing this to happen?  Any fixes?
