### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) ### Search before asking - [X] I have searched in the [issues](https://github.com/apache/incubator-uniffle/issues?q=is%3Aissue) and found no similar issues. ### Describe the bug In high-pressure scenarios, inaccurate flow control(usedMemory? preAllocatedMemory?) leads to Shuffle server OOM.  The SQL used to reproduce the bug: tpcds： select * from ( select s.*,c.* from store_sales s join customer c on s.ss_customer_sk=c.c_customer_sk ) sc DISTRIBUTE BY sc.ss_customer_sk,sc.ss_item_sk; ### Affects Version(s) master ### Uniffle Server Log Output ```logtalk [2024-01-19 03:18:50.483] [Grpc-714] [DEBUG] org.apache.uniffle.server.buffer.ShuffleBufferManager.requireMemory - Require memory succeeded with 1023891 bytes, usedMemory[117888810505] include preAllocation[180869913], inFlushSize[110004009963] [2024-01-19 03:18:50.485] [Grpc-19] [DEBUG] org.apache.uniffle.server.buffer.ShuffleBufferManager.requireMemory - Require memory succeeded with 3093288 bytes, usedMemory[117891903793] include preAllocation[183963201], inFlushSize[110004009963] [2024-01-19 03:18:50.485] [epollEventLoopGroup-3-19] [DEBUG] org.apache.uniffle.server.netty.ShuffleServerNettyHandler.handleSendShuffleDataRequest - Cache Shuffle Data for appId[application_1703049085550_1651917_1705170927963], shuffleId[0], cost 0 ms with 52 blocks and 1189625 bytes [2024-01-19 03:18:50.487] [epollEventLoopGroup-3-44] [WARN] org.apache.uniffle.common.netty.handle.TransportChannelHandler.exceptionCaught - Exception in connection from /9.23.12.144:45176 io.netty.util.internal.OutOfDirectMemoryError: failed to allocate 4194304 byte(s) of direct memory (used: 171798691840, max: 171798691840) at io.netty.util.internal.PlatformDependent.incrementMemoryCounter(PlatformDependent.java:843) at io.netty.util.internal.PlatformDependent.allocateDirectNoCleaner(PlatformDependent.java:772) at io.netty.buffer.PoolArena$DirectArena.allocateDirect(PoolArena.java:710) at io.netty.buffer.PoolArena$DirectArena.newChunk(PoolArena.java:685) at io.netty.buffer.PoolArena.allocateNormal(PoolArena.java:212) at io.netty.buffer.PoolArena.tcacheAllocateNormal(PoolArena.java:194) at io.netty.buffer.PoolArena.allocate(PoolArena.java:136) at io.netty.buffer.PoolArena.allocate(PoolArena.java:126) at io.netty.buffer.PooledByteBufAllocator.newDirectBuffer(PooledByteBufAllocator.java:397) at io.netty.buffer.AbstractByteBufAllocator.directBuffer(AbstractByteBufAllocator.java:188) at io.netty.buffer.AbstractByteBufAllocator.directBuffer(AbstractByteBufAllocator.java:179) at org.apache.uniffle.common.netty.protocol.Decoders.decodeShuffleBlockInfo(Decoders.java:50) at org.apache.uniffle.common.netty.protocol.SendShuffleDataRequest.decodePartitionData(SendShuffleDataRequest.java:92) at org.apache.uniffle.common.netty.protocol.SendShuffleDataRequest.decode(SendShuffleDataRequest.java:104) at org.apache.uniffle.common.netty.protocol.Message.decode(Message.java:145) at org.apache.uniffle.common.netty.TransportFrameDecoder.channelRead(TransportFrameDecoder.java:72) at io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:444) at io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:420) at io.netty.channel.AbstractChannelHandlerContext.fireChannelRead(AbstractChannelHandlerContext.java:412) at io.netty.channel.DefaultChannelPipeline$HeadContext.channelRead(DefaultChannelPipeline.java:1410) at io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:440) at io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:420) at io.netty.channel.DefaultChannelPipeline.fireChannelRead(DefaultChannelPipeline.java:919) at io.netty.channel.epoll.AbstractEpollStreamChannel$EpollStreamUnsafe.epollInReady(AbstractEpollStreamChannel.java:800) at io.netty.channel.epoll.EpollEventLoop.processReady(EpollEventLoop.java:509) at io.netty.channel.epoll.EpollEventLoop.run(EpollEventLoop.java:407) at io.netty.util.concurrent.SingleThreadEventExecutor$4.run(SingleThreadEventExecutor.java:997) at io.netty.util.internal.ThreadExecutorMap$2.run(ThreadExecutorMap.java:74) at io.netty.util.concurrent.FastThreadLocalRunnable.run(FastThreadLocalRunnable.java:30) at java.lang.Thread.run(Thread.java:750) ``` ### Uniffle Engine Log Output _No response_ ### Uniffle Server Configurations ```yaml xmx：120g capacity：110g read.capacity：20g max_direct_mem：160g rss.server.netty.epoll.enable true rss.rpc.server.type GRPC_NETTY ``` ### Uniffle Engine Configurations ```yaml set spark.sql.files.maxPartitionBytes=1073741824; set spark.executor.cores=8; set spark.task.cpus=4; set spark.executor.memory=49g; set spark.driver.memory=20g; set spark.dynamicAllocation.maxExecutors=150; set spark.dynamicAllocation.minExecutors=150; set spark.rss.client.type = GRPC_NETTY; set spark.rss.client.netty.io.mode = EPOLL; ``` ### Additional context _No response_ ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! -- This is an automated message from the Apache Git Service.
