[REBOL] How safe is catch []

From: sqlab:gmx at: 25-Apr-2005 10:36

How safe is catch? I have some rebol applications serving message communication (around 1000 to 2000 messages per day mostly) running for more than half a year on Windows2000 Server without interruption since the last update of the OS for security reasons. Recently I had to add some message splitting: one-message --> [message-part-1 message-part-2 message-part-3] I used a construct similar to this forever [ until [new-messages-available] foreach message new-messages [ catch [ if not important [throw] do-some-heavy-message-processing-and data-completion-using-odbc if some-tests [throw] message-parts: split-messages message until [ catch [ message: first message-parts do-more-conversions if other-tests [throw] deliver message emtpy? message-parts: next message-parts ] ] ] ] ] Now I saw two crashes in one day. I was somehow able to reproduce the crash Invalid data type during recycle by playing again the history of one to two weeks. But the crash happened always processing another message. As I had seen in the past instable behaviour with constructs like this foreach ... [ catch [ .. data: any [ a b throw ] .. .. ] ] I replaced the inner catch with statements like this if not other-tests [ deliver message ] and the crash went away. Now I am curious if someone else encountered the same behaviour too? -- +++ GMX - Die erste Adresse für Mail, Message, More +++ 1 GB Mailbox bereits in GMX FreeMail
