io.netty.channel.DefaultChannelPipeline - An exceptionCaught() event was fired, and it reached at the tail of the pipeline. It usually means the last handler in the pipeline did not handle the exception. java.lang.OutOfMemoryError: Direct buffer memory at java.base/java.nio.Bits.reserveMemory(Bits.java:175) at java.base/java.nio.DirectByteBuffer.<init>(DirectByteBuffer.java:118) at java.base/java.nio.ByteBuffer.allocateDirect(ByteBuffer.java:317) at io.netty.buffer.PoolArena$DirectArena.allocateDirect(PoolArena.java:769) at io.netty.buffer.PoolArena$DirectArena.newChunk(PoolArena.java:745) at io.netty.buffer.PoolArena.allocateNormal(PoolArena.java:244) at io.netty.buffer.PoolArena.allocate(PoolArena.java:226) at io.netty.buffer.PoolArena.allocate(PoolArena.java:146) at io.netty.buffer.PooledByteBufAllocator.newDirectBuffer(PooledByteBufAllocator.java:332) at io.netty.buffer.AbstractByteBufAllocator.directBuffer(AbstractByteBufAllocator.java:185) at io.netty.buffer.AbstractByteBufAllocator.directBuffer(AbstractByteBufAllocator.java:176) at io.netty.buffer.AbstractByteBufAllocator.ioBuffer(AbstractByteBufAllocator.java:137) at io.netty.channel.DefaultMaxMessagesRecvByteBufAllocator$MaxMessageHandle.allocate(DefaultMaxMessagesRecvByteBufAllocator.java:114) at io.netty.channel.nio.AbstractNioByteChannel$NioByteUnsafe.read(AbstractNioByteChannel.java:147) at io.netty.channel.nio.NioEventLoop.processSelectedKey(NioEventLoop.java:677) at io.netty.channel.nio.NioEventLoop.processSelectedKeysOptimized(NioEventLoop.java:612) at io.netty.channel.nio.NioEventLoop.processSelectedKeys(NioEventLoop.java:529) at io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:491) at io.netty.util.concurrent.SingleThreadEventExecutor$5.run(SingleThreadEventExecutor.java:905) at io.netty.util.concurrent.FastThreadLocalRunnable.run(FastThreadLocalRunnable.java:30) at java.base/java.lang.Thread.run(Thread.java:834)
