I added this to the wiki faq. It seemed tricky enough to warrent passing along.
http://www.mimedefang.org/kwiki/index.cgi?FilterCleanup If you read the mimedefang-filter man page, you will see that filter_cleanup is called on exit, but that is just the normal case. A mimedefang-multiplexor slave-busy-time-out results in a term signal without filter_cleanup. To further complicate matters, the embedded perl note in the man page regarding filter_initialize and the scope of handles also applies to signal handlers. That is to say you need to add: $SIG{"TERM"} = \&filter_cleanup ; To filter_initialize() where you open the handles if you need to make sure they are consistently closed on exit in filter_cleanup. -- Ray Ferguson _______________________________________________ NOTE: If there is a disclaimer or other legal boilerplate in the above message, it is NULL AND VOID.
