Why does the terminal freeze after issuing a command?

Question

linux

[[email protected]: ~]$ ls -la
And then nothing... Doesn't respond to ctrl+c, ctrl+z. Also with SOME and other commands (lsof, kill).

Answer 1

Most likely a problem with a disk / flash drive or a fallen network drive

Answer 2

Ls - la is more like a large list of files in a directory.
Lsof - many open files or sockets
try to output only part of the files from the top:
ls -la |head
