> 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!
