FOrtunately we are not yet in production .Having the console appender there was a copy/paste error. But I think the issue is more than slowness. The appender is not making progress. thread stack dumps after 30 min , 1 hr , 1.5 hr etc produce the same stack. ConsoleTarget calls System.out. Perhaps there is a JVM / driver /docker issue here. It might be worthwhile to update the documentation to say that "Do not use the ConsoleAppender if you are a Deamon process and there is no console to write to" |
