> 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.
