Possible a zombie (or hidden/forgotten) process is running though the log indicates local. Had been using pg_admin3 for testing and somehow ended up with a possible zombie process there so maybe...

In the target directory the most recent WAL files is only ~2MB in size (can't check the pg_xlog directory at the moment). My guess is size quota on target but cannot check at the moment. Turned off WAL archive and restarted the server. Restarted a couple of times until I remembered to shutdown all the other applications.

Looking at my process viewer I saw a Java process running (with Catalina...) even though I supposedly shutdown Tomcat. Since Tomcat wasn't working anyway I decided to just kill the process then restart PostgreSQL...no more spurious error message. Restarted Tomcat and I can now hit my Servlet.

Just need to get the base backup and WAL shipping enabled again. Assuming since I disabled it, and just ran a pg_dump while everything was disconnected, that I can basically throw out the shipped WAL files?

Still kinda at a loss for root cause and deciding whether there still may be an underlying problem. Thoughts are welcome but I'm likely to seek professional help on this one regardless.

Thanks for listening.
