 I upgraded and patched (using luupgrade) a LDom yesterday.
Here are the current levels:

uname -a
SunOS sys1 5.10 Generic_144488-04 sun4v sparc SUNW,SPARC-Enterprise-T5220

cat /etc/release
                      Solaris 10 10/09 s10s_u8wos_08a SPARC

After a reconfigure reboot I was able the open an ssh session (PuTTY) and everything seemed OK.  Later I received the following message on the console:

Dec  8 18:16:20 sys1 sshd[1397]: monitor fatal: protocol error during kex, no DH_GEX_REQUEST: 254

Today I can not open new ssh sessions and the session that I had open yesterday is dead.

Howdy, Stranger!
