ISPConfig 3.0.4.6 Web domain backup issue

[autogun]

Hello,

I have one website that is being back'ed-up by ISPConfig built-in backup function which is under Sites - Websites - <domain.com> - Backup tab.

For some unknown reason, backup of this website looks like this:

ls -la
total 2099212
drwxr-x---  2 web55 client15       4096 2012-11-05 01:11 .
drwxr-xr-x 23 root  root           4096 2012-07-31 17:45 ..
-rw-r--r--  1 root  root     2147483647 2012-11-05 01:20 ziwNZpIi

There's nothing I can do with that file, seems like it's damaged.

While other backups are looking and working fine:

ls -la
total 1978692
drwxr-x---  2 web4 client4      4096 2012-11-05 00:47 .
drwxr-xr-x 23 root root         4096 2012-07-31 17:45 ..
-rwxr-x---  1 web4 client4 404928190 2012-11-05 00:47 web.1.zip

-rwxr-x---  1 web4 client4 405014045 2012-11-02 00:57 web.4.zip
-rwxr-x---  1 web4 client4 404377378 2012-11-01 00:55 web.5.zip

Can this somehow be resolved?
