- While
the use of Logwatch may be related to security (as in auditing practices) your question isn't a Linux Security question but one about an error or bug in the application itself. Hence your thread is moved to the Software forum to ensure it gets the exposure it needs.
- The current version of Logwatch is
7.4.1. This may be of relevance if that fixes things for you. Do check out its changelog.
- "Unopened file handle" means the file was closed. This may be a bug. See if
http://sourceforge.net/p/logwatch/bugs/ already contains a report, else report it yourself.
