Hi, we use the OTRS-cache-mechanismn for LDAP-queries among others. The problem is that the Cache-directory /opt/otrs/var/tmp/Cache gets filled up with many files. The TTL of these files is mostly expired, so these files could be erased. So far I found out, a expired cache-file is overwritten with the new results if exactly the same query is asked again - this makes sense. But I found no possiblility to erase every cache-file which is expired. Due to so many files within my Cache-directory, I would have to erase the content of the whole Cache-directory, e.g. through writting a cronjob which make use of Kernel::System::Cache::CleanUp.
