Jared Ocker commented on TS-1975:
---------------------------------
Unfortunately, I don't know how to initiate it, it just happens multiple times
per day. Below is a listing of our September log output from {{grep FATAL
manager.log}} showing the frequency on a test server with light traffic. I've
not seen any core dumps. Do you have any suggestions for debug tags? Even
excluding some of the most verbose tags with {{CONFIG
proxy.config.diags.debug.tags STRING ^(?!.\*dir_clean|stats|log.*|http)}} still
generates a ton of output.
