config save hangs ...

You get returned to the prompt when the command completes:

 

 

[hoolio@test1_6400:Active] ~ b config save test.ucs

 

Saving active configuration...

 

[hoolio@test1_6400:Active] ~

 

 

A UCS archive is a gzip'd tar archive. So you can use the tar command on the LTM command line or a Zip utility on your workstation to see if the UCS is a valid tar archive:

 

 

[hoolio@test1_6400:Active] ~ tar tvfz /var/local/ucs/test.ucs |less

 

 

This should list the files in the archive.

 

 

A 238kB UCS isn't very large. I wouldn't expect it to take more than a minute to create a UCS of that size. In 9.4.7, LTM returns an error if the config save process fails:

 

 

[hoolio@test1_6400:Active] ~ b config save test.ucs

 

Saving active configuration...

BIGpipe parsing error:

If you're not able to test by loading the UCS and not sure if the UCS that's being created is valid, you could open a case with F5 Support and see if they could load your UCS on a test unit.
