[jira] [Created] (LOG4J2-1116) upgrade to log4j2 causes too
frequent minor gc
Mingjiang Shi created LOG4J2-1116:
-------------------------------------
Summary: upgrade to log4j2 causes too frequent minor gc
Key: LOG4J2-1116
URL: https://issues.apache.org/jira/browse/LOG4J2-1116
Project: Log4j 2
Issue Type: Bug
Components: Core
Affects Versions: 2.3
Environment: jdk1.6
slf4j 1.7.9
log4j2.3
Reporter: Mingjiang Shi
Priority: Critical
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!
