Bit of progress, but something is still not quite right. Verified permissions on the cache directory and ran the command to remove files (directories were still there). Removed the lock files and re-ran the config. I'm not longer seeing the errors come up with kaltlog running, but the sanity test fails on the Create Partner step. All other tests up to that point pass.
I noticed while running the sanity test that it downloads php5full, which I don't recall seeing before (but I could be wrong). The output on the "Space on /opt/kaltura/web" step shows:

I am able to login to the admin console successfully again. So definitely a step in the right direction.
