Remko Popma commented on LOG4J2-1116:
-------------------------------------
The current docs for garbage-free logging (LOG4J2-1297) assume the web-friendly
ThreadLocals won't be ready before the next release, but of course I'd be happy
to change that.
I haven't looked at this for a while. Can you remind me what is still remaining?
> Web app-friendly thread locals for gc-free logging (was: upgrade to log4j2
> causes too frequent minor gc)

> We used slf4j+log1.2 in our spring web application. Due to the log4j1.0
> performance issue, we upgrade it to log4j2. When it goes to production, it
> experienced very frequent minor gc (once per second) even though the eden
> area is not full. For example, the eden area just occupied 10%, the minor gc
> also happens. The issue disappears when rolling back to log4j1.2.
> Can anyone show some hints on diagnose this issue? Thanks!
