-----------------------------------
Summary: Build Server OOM
Key: KYLIN-4333
URL: https://issues.apache.org/jira/browse/KYLIN-4333
Project: Kylin
Issue Type: Improvement
Components: Job Engine, Query Engine
Affects Versions: v3.0.0-alpha2, v3.0.0-beta, v3.0.0
Reporter: wangxiaojing
Kylin 3 frequently appears full GC or even OOM, and build server appears OOM
almost every 4 days. Query server also has full GC, but it appears less
frequently than build server.
We have about 2000 cubes on this Kylin cluster (3 build servers and 3 query
servers , 32g memory per server)。
Through mat analysis of dump, there may be a memory leak.
