我之前在跑步atop。它正在工作，但后来它终止了，退出状态为 53。
$ atop
$ echo $?
53
这是一个错误吗atop？或者我的系统出现故障？
先发制人的额外细节:-)
我检查了内核日志（dmesg）。我什么也没找到具体来说令人震惊，但也有一些错误。见下文。
这台笔记本电脑已经可靠使用了几个月。内核没有被“污染”，因此没有内核 WARN 或 OOPS 消息。
$ cat /proc/sys/kernel/tainted
0
$ rpm -q atop
atop-2.3.0-10.fc28.x86_64
$ uname -r # My kernel version
5.1.6-200.fc29.x86_64
dmesgatop提醒我，我最近将计算机从睡眠状态唤醒，并在它进入睡眠状态之前启动。
dmesg还会发生显示 USB 和 FAT 错误的情况，因为在此期间我与连接不良的 USB 记忆棒失去了连接。
从挂起恢复期间有一些硬件消息。但在过去的几个月里，我没有遇到任何用户可见的睡眠/唤醒问题。
还有一些早期的dmesg错误。

答案1
这是 中的一个错误atop。当出现致命错误时，无法打印错误消息。我有报告了该错误到 atop 项目。
错误是我atop在将目录 ( ) 更改cd为已安装的 USB 后碰巧运行...后来我与已安装的 USB 失去了连接。
src/atop$ grep -r 'exit[ ]*[(]' .
...
various.c
577: exit(13);
590: exit(exitcode);
...
src/atop$ grep -r '53' .
...
photosyst.c
101:** Revision 1.16 2004/05/06 09:53:31 gerlof
107:** Revision 1.14 2003/07/08 13:53:21 gerlof
305: cleanstop(53);
...
在函数中photosyst()：
if ( getcwd(origdir, sizeof origdir) == NULL)
{
perror("save current dir");
cleanstop(53);
}
我懂了atop 尝试打印错误消息。但后来我希望cleanstop()恢复原来的屏幕。所以它消除了错误消息:-)。
