Huge files asset/var/tmp/pdf-text.extract....txt


When importing Assets (PDF) through the REST-API, the system generates huge files in assets/var/tmp/ , named pdf-text-extract-[hash].txt. Every file is writen to 17GB, then a next one is generated.
Only 1.4GB of PDF where imported.
I haven’t found anything related to this files, so anyone know what these files are for and if this is a desired behavoir?


Obviously these files are created by the search index. The maintenance job in our testsystem wasn’t running. After activation of the job the files were processed and deleted.
