jemalloc dump 内存

hi,社区的各位,是否有配置过jemalloc?

目前在docker容器中放入编译过后的jemalloc,在flink的配置文件加入如下配置

containerized.taskmanager.env.LD_PRELOAD: /opt/jemalloc/lib/libjemalloc.so
   containerized.taskmanager.env.MALLOC_CONF: prof:true,lg_prof_interval:25,lg_prof_sample:17,prof_prefix:/opt/state/jeprof.out

结果生成不到对应的heap文件, /opt/state挂载在宿主机的磁盘上,权限给了。

请问该如何操作才可以生产内存dump呢?
