我的 linux (debian) 服务器上有一些奇怪的行为。命令的输出未完全显示有时。例如top只会这样显示。

运行git只会输出这个。
user@srvapp1:$ git
usage: git [--version] [--help] [-C <path>] [-c name=value]
[--exec-path[=<path>]] [--html-path] [--man-path] [--info-path]
[-p | --paginate | --no-pager] [--no-replace-objects] [--bare]
[--git-dir=<path>] [--work-tree=<path>] [--namespace=<name>]
<command> [<args>]
These are common Git commands used in various situations:
start a working area (see also: git help tutorial)
clone Clone a repository into a new directory
init Create an empty Git repository or reinitialize an existing one
work on the current change (see also: git help everyday)
add Add file contents to the index
mv Move or rename a file, a directory, or a symlink
检查内存free -h给了我。

我还可以检查什么，或者此行为是否暗示硬件问题？
