patchsvr apparently broken again

I have a T-2000 running Solaris 10 acting as patch proxy. I just successfully patched this system up to latest everything. Some of the other systems have been sucessfully patched to latest as well. Now, after rebooting the patch proxy, I get the same symptoms on all systems. That is, smpatch analyze still works, but when I try to update/download patches, I get "WARNING: The installer cannot find the patch" or "This patch could not be found" depending on what command I run. Real helpful diagnostic that is. Is there a "look harder" option for smpatch?

A check of the latest localhost_log on the patch proxy reveals:
