I reverted the connections and discon from on back to off, and did a postgresql reload as well as pg_reload_conf(). For both servers. db4 the log file is getting updated db1 nothing. I thought the file was locked or some perms may have changed and I deleted the postgresql-9.0-main.log file. It didn't create a new log file until i did a postgresql reload. It created the new file, but still nothing getting written to it.

From the bin directory you can do: pg_ctl reload -D (followed by the data dierctory)
