Killed

之前是正常接收和出块的消息。然后后面不知为何出错……启动命令里已经加上

Code: [Select]

--replay了。
另外进程被kill之后似乎见证人没有自动下线……？因此错过了十几个block generation了……

偶尔出现 unlinkable block 属于正常情况，特别是你的节点或者他人节点网络不稳定的时候，以及重新从头开始同步的时候。
出于网络整体安全方面考虑，被动触发离线需要等比较长一段时间，现在测试网里这个参数是3小时。具体参数可以用get_global_properties命令看。

另外，kill是你主动发起的？如果不是，可能原因是内存不足。

试了几次都出现丢块，回头看记录的时候发现错误提示是这个。
不过在运行的时候已经把privkey也追加到运行参数里面了，可能是什么原因导致出块失败了呢。
有几次启动程序都会出现 Not producing block because production is disabled until we receive a recent block (see: --enable-stale-production)，似乎需要反复启动几次程序才能接收其他人的出块。

运行的指令是这个（私钥用privkey代替了）：

Code: [Select]

./yoyow_node --rpc-endpoint -w 209420985 -private-key '["YYW82qoU3N6dwoRHRM4y3QhGF3XQrrrcSUCnmDJJZondR7GSfaPfY","privkey"]'

你上面的错误提示有两种，一个是 because I don't have the private key ，那么是参数设错了，命令里私钥参数是 --private-key 最前面是两个横杠，不是一个

另一种错 production is disabled until we receive a recent block 有可能是系统时间不同步；如果时间已经同步了，那就要等一会，可以到 client 里面用 info 或者 get_dynamic_global_properties 命令看同步状态， head_block_num , head_block_age 和 time 这几个值，是否是最新。

如果 node 里出现 unlinkable 的问题，目前的临时解决方案是启动命令里加一个 --replay 参数
./yoyow_node --rpc-endpoint -w 209420985 --private-key '["YYW82qoU3N6dwoRHRM4y3QhGF3XQrrrcSUCnmDJJZondR7GSfaPfY","privkey"]' --replay
