Issue with adop fs_clone after upgrade to R12.2.3 on VIS instance

Question

I have installed EBS R12.2.0 Vision instance on Oracle Linux Server release 6.5 x86-64 with Unbreakable Enterprise Kernel release 3 (3.8.13-16.2.2.el6uek.x86_64) and then updated to R12.2.3.  Everything went smooth with the initial install, the AD and TXK patches, and the adop patching cycle for 12.2.3 update.  I'm having an issue with the running fs_clone which is the first post-update step from doc 1586214.1.  The other adop phases ran OK see below.  Also below is the error I'm getting and want to know if anyone has experienced this or any ideas?  I've googled and searched MOS but can't find a direct hit.  I'm new to adop and struggling to troubleshoot this....any help would be appreciated. I've run the fs_clone phase a couple times but got the same result.
adop -status -detail (this is the R12.2.3 update cycle).  All steps seems OK here.

Randy,
Looks like you need to add more space to /tmp directory as I see the following entries in CLONE*.error file.
CLONE2013-12-28_12-41-01PM.error:
