kill 命令再次執行時會導致以下錯誤。
pkill -9 nodeos or kill -9 {pid}
database dirty flag set (likely due to unclean shutdown): replay required當重新運行nodeos時，必須使用--replay-blockchain命令忽略它。
讓我們安全的結束nodeos 進程
This appears to be two different issues.
Startup after a crash or ungraceful shutdown nearly always fails due to corruption of the boost shared memory cache of the in-memory database. --resync is required to clean up the mess.
For normal shutdown, never kill with -9. Always use either the default (no argument) signal (which is SIGTERM) or SIGINT. Numerically, those are 15 and 2, respectively.
pkill nodeos | Safe
pkill -15 nodeos | Safe
pkill -2 nodeos | Safe
pkill -TERM nodeos | Safe
pkill -SIGTERM nodeos | Safe
pkill -INT nodeos | Safe
pkill -SIGINT nodeos | Safe
pkill -9 nodeos | Not Safe
pkill -KILL nodeos | Not Safe
pkill -SIGKILL nodeos | Not Safe
The core dump is a different problem. That looks like a corrupted network packet, specifically a signed_block_summary. Summary messages are being eliminated from the protocol, so this particular error will no longer be possible soon.參考自：github
