As you can see, periodically we get strange "ls" behaviour which happens repeatedly until i log out and in again, at which point it works.

Sometimes it works first time, and other times it errors until i log out and in again.

I hope someone knows what's causing this, because it's a nightmare! lol

Thanks in advance, people! Smilie Smilie

could it be tied into these messages that we're seeing in "/var/log/messages" and "/var/log/warn"?

Code:
stg-backup:/var/log # tail messages

This may be a red herring, posting these messages, but they are also strange and so may be somehow related...

strangely, i'm beginning to think it's some strange environment problem because i just suffered the problem again, and this time decided to open a second terminal to see if the problem could exist in two separate terminals.

Here are the results from both terminals:

stg-backup:/rmt/project2 #

as you can see, i had two terminals open on the same machine at exactly the same time, both in the same automounted NFS directory, running exactly the same command.

One terminal failed, and the other worked.

Therefore this cannot be a hardware problem, right?

to prove that this is not a coincidence, i ran the same test three more times, and got exactly the same results - TERMINAL 1 was "broken" and TERMINAL 2 was working.

I then logged out on TERMINAL 1 and logged back in again and it works again:

so now i'm really confused...

The annoying thing is that i have also just noticed that this problem is causing some of the cron jobs that access remote NFS volumes to fail as well!

Argh!

Someone help me, please! lol

Do you know how to fix that yet?
It seems that we are seeing the same thing here.
Thanks
