Thanks for that.
This script divides whole text file using \f and moves structure one line down. I know that something went wrong because the structure of the file has not been changed.
In Live, I have dual core and 32 GB and I have a problem on the test server there is dual core with 5GB and we do not have a problem. Processes are the same on Live and on the test server. Files are not veeery big from 19KB to 600KB. There is no problem with one single file.

You mentioned repair. Do you know if I need to move my license if I do a repair of Planet Press?
