I've been reading other SF threads regarding ls not returning results or freezing and stalling terminal sessions and it appears they usually the fault of network problems. My problem however, occurs both over remote SSH sessions but also if I am physically at the server itself...

I just installed CentOS 5.4 on one of our servers. I'm setting up some rdiff-backup scripts and when I downloaded librsync and untared it, thats when I started seeing some weird behavior with ls -l.

wget http://sourceforge.net/projects/librsync/files/librsync/0.9.7/librsync-0.9.7.tar.gz/download /tmp

cd /tmp

tar -xzf librsync-0.9.7.tar.gz

Simple enough. To view the files in this directory I did this:

ls

results:

librsync-0.9.7  librsync-0.9.7.tar.gz

Now, if I ls -l, my terminal freezes. I have to re-ssh in to keep going. After reading SF threads, I thought it was network related.

So I was extremely surprised to go sit down at the server itself and see the exact same thing happen... So its obviously not a network issues.

Even if I ls /tmp/librsync-0.9.7, my terminal freezes just the same...

Next I did an strace and got this (warning: wall of text coming....):

strace ls -l /tmp

And thats where it stops, right there after that last 120000.... Using strace, I can obviously CTRL+C to keep going. But like I said, normally the terminal completely freezes.

Anyone have any clues?
