好的，谢谢回复，那请问下 taskmanager.memory.task.off-heap.size 这个参数可以通过 下面代码动态设置吗？
streamTableEnv.getConfig().getConfiguration().setString(key, value); ________________________________ 发件人: Xintong Song <tonysong...@gmail.com> 发送时间: 2020年11月16日 10:59 收件人: user-zh <user-zh@flink.apache.org> 主题: Re: flink-1.11.2 的 内存溢出问题 那应该不存在内存泄露的问题。应该就是 job 需要的 direct 内存不够用。 可以尝试按报错信息中提示的，把 `taskmanager.memory.task.off-heap.size` 调大看看。 只调大 TM 的总内存没有用的，不会增加 job 可用的 direct 内存。 Thank you~ Xintong Song On Mon, Nov 16, 2020 at 6:38 PM 史 正超 <shizhengc...@outlook.com> wrote: > flink-on-yarn . per-job模式，重启是kafka的group.id > 没变，应该是接着offset消费的，但是任务启动不起来。不知道是不是一段时间后，积压导致的。 > ________________________________ > 发件人: Xintong Song <tonysong...@gmail.com> > 发送时间: 2020年11月16日 10:11 > 收件人: user-zh <user-zh@flink.apache.org> > 主题: Re: flink-1.11.2 的 内存溢出问题 > > 是什么部署模式呢？standalone？ > 之前任务运行一段时间报错之后，重新运行的时候是所有 TM 都重启了吗？还是有复用之前的 TM？ > > Thank you~ > > Xintong Song > > > > On Mon, Nov 16, 2020 at 5:53 PM 史 正超 <shizhengc...@outlook.com> wrote: > > > 使用的是rocksdb, 并行度是5，1个tm, 5个slot，tm 内存给 > > 10G，启动任务报下面的错误。之前有启动成功过，运行一段时间后，也是报内存溢出，然后接成原来的offset启动任务，直接启动不起来了。 > > > > 2020-11-16 17:44:52 > > java.lang.OutOfMemoryError: Direct buffer memory.
