We are having an issue where a CD is issued for a dataset level and the client hangs. At this level, the first thing that shows up is a GDG base. Here is what happens:
$ sftp fsftpyxz@161.215.54.19
Connecting to 161.215.54.19...
sftp> cd //ZEEXOTF.TFEX.ZETF500.ARCOUT #-dp- prompt returns immediately
sftp> cd //ZEEXOTF #-dp- prompt returns immediately
sftp> cd //ZEEXOTF.TFEX #-dp- prompt returns immediately
sftp> cd //ZEEXOTF.TFEX.ZETF500 #-dp- stalls, prompt doesn't return
Killed by signal 15. #-dp- had to kill process from client machine
Connection closed
Here is an ISPF 3.4 display of this level:

We are running Co:Z cozsftp version: 1.3.2 (5.0p1) 2009-07-14.
Any ideas?

CD Hangs the SFTP Client
Jerry,
You are running a somewhat old release, but I'm not sure what the problem might be.
If you look at the OMVS job for this userid and program "sftp-server", can you tell if it is hung or looping?
It could be that it is hung somewhere in catalog search (IGGCSI00), based on what you are doing, but I'm not sure why that would be. I assume that ZEEXOTF.TFEX.ZETF500.ARCOUT is a GDG base entry. which shouldn't be a problem.
Can you capture a trace? You can turn it on from the remote client like this:
Kill it from the client when it hangs and then get the /tmp/sftp-server.xx.yy.log file for this session (which might be a different name depending on your configuration). Please email this to info@dovetail.com and we'll take a look.

I have a user having the same issue. I am running coz 1.7.5. If i remove a gdg or 2 then he works fine. Could this be the same issue.
Re: CD Hangs the SFTP Client
I have done further tests and below is what i found.
The GDG base consists of 15 files. When this maximum is reached, the user hangs on the CD command. The workaround i put in place is that i created a dummy file and placed it above the GDG base files, now the user works fine.

Re: CD Hangs the SFTP Client
This is likely the same bug as reported earlier in this thread, which was fixed in release 1.7.7.
