seata server 疑问

centos 7.9.2009

问题：seata server 启动后过一段时间报错。我只看到到在 seata server 端启动的时候，在初始化 netty 时，有这样一个调用链：【io.seata.core.rpc.netty.NettyRemotingServer#init】-->【io.seata.core.rpc.netty.AbstractNettyRemotingServer#init】-->【io.seata.core.rpc.netty.NettyServerBootstrap#start】中【new ProtocolV1Decoder()】时指定了帧最大长度为【io.seata.core.protocol.ProtocolConstants#MAX_FRAME_LENGTH，8M】。不晓得是不是这个包大小的设置问题。

堆栈信息如下：

11:34:01.632  INFO --- [ttyServerNIOWorker_1_6_16] i.s.c.r.n.AbstractNettyRemotingServer    : channel exx:Adjusted frame length exceeds 8388608: 539972468 - discarded,channel:[id: 0x499841b2, L:/192.168.73.127:9091 - R:/192.168.74.33:49174]
