Question

在此先感谢您的协助

我为各种加密货币运行原始的QT钱包（基于命令行）。今年早些时候，我将它们设置为自定义的systemd服务，这是非常宝贵的。就像所有常规服务一样，它会启动它们并通过系统将其关闭。我最近发现了一个特别是blackcoin的问题。

该服务过去运行良好（我不知道在发现它之前已经停机了多长时间）

如果我在execstart =命令之后手动运行命令，则一切正常。如果我尝试启动服务（通过systemctl start blackcoin），它将失败，并显示以下服务状态：

blackcoin.service - blackcoin wallet daemon
Loaded: loaded (/etc/systemd/system/blackcoin.service; enabled; vendor preset: enabled)
Active: failed (Result: core-dump) since Tue 2018-11-20 10:44:01 MST; 2h 51min ago

Main PID: 12283 (code=dumped, signal=ABRT)

Nov 20 10:44:01 knox systemd[1]: blackcoin.service: Failed with result 'core-dump'.
Nov 20 10:44:01 knox systemd[1]: Failed to start blackcoin wallet daemon.

这是systemd服务的主体：

这是blackcoin.conf包含的内容：

rpcuser=somedude
rpcpassword=12345 (please don't rob my coins!)

# Wallets
wallet=wallet-blackcoin.dat


pid=/run/blackcoind/blackcoind.pid

rpcport=56111
port=56112

我将继续测试，并将发布我发现的任何新内容。感谢您的光临！
