Using SLES10-SP3/OES2-SP3. Been using this server for a year or so. No recent updates.

When trying to login as root to the console/SSH/VNC, I get the login prompt, but after entering login name it takes a minute or two for password promt to appear. after entering password, console/VNC just goes to blue screen (not BSOD or anything, just the desktop but with no access) and SSH does not show command prompt.

any other way to access to I can check out? and when doing so, what I might be looking for? check disk space a couple weeks ago and all were OK.
