I've patched my 4th OES SP2 - Linux server today using:

# rug pin --entire-channel oes

Everything went fine, but one patch fails to install.

server:/var/log # rug pin oes:patch-11255

Warning: Error installing patch 'patch-11255'.

server:/var/log # rug ping

WHERE DO I START TROUBLE-SHOOTING THIS. Log files? Any tids?
thanks,
