Sun's smpatch

I had a problem with smpatch where it seemed to just hang when downloading patches - it didn't look like it was doing anything and it had created a temp file in /var/sadm/spool, which in my case was 122856-02.jar.tmp

Stopping and restarting the process then ended up with a second temp file - 122911-02.jar.tmp and once again, it wasn't looking like it was doing anything.
I deleted both these temp files and downloaded the signed versions of the patches manually, copied them over to the /var/sadm/spool directory and kicked off the whole process again.

Now it looks like it's going along properly, validating the new downloads and generally behaving itself...
