Directory watcher gateway stops seeing files added after working fine for awhile

forums_noreply@adobe.com — Wed, 17 Nov 2010 15:52:05 GMT

We have a directory watcher gateway that has worked quite well in the past, but over the past couple days has started having problems. What seems to happen is that the gateway cfc stops firing when a file is added to a directory. Stopping and restarting the gateway doesn't fix the problem. However we are running 4 instances on the server, so I removed the gateway from one instance and added it to another. Things started working again. Then the next day, the new gateway stopped working. Moved it back to the original instance, and it's working again.

We also have a scheduled task that cleans up files that the gateway misses, it runs every 3 minutes. The gateway does log some "file does not exist" errors but it seems to only happen when the scheduled task runs - that is, it seems like the gateway doesn't notice the files until another process tries to do something with them!

Incidentally we have been doing a pretty high volume of traffic lately and the server has had some other issues (another process has brought it down multiple times in the past week) - so the server has actually been restarted a few times lately (it's in a cluster of 2). I'm not sure how these things would really affect the gateway's operaion though.

Does anyone know what might be going on here? Thanks in advance!

FlateDecode error removing a watermark from a PDF

forums_noreply@adobe.com — Tue, 05 Oct 2010 16:11:29 GMT

We are running CF8.01(.195765, Java 1.6.0_13) on Windows Server 2003 R2. We have a feature where we remove a watermark from a pdf using CFPDF action="removewatermark". Occasionally (it's only happened a couple times since we released this feature last week) we get an error with the message "FlateDecode Filter". There are no other details about the error or what it means. I Googled FlateDecode and it seems like it's some sort of PDF filter that CF does not support. The file we're removing the watermark from would be a user-uploaded file that may be created by any application in any pdf format. I'd like to find out if there's a way we can detect the filter to handle the error, or if perhaps there's something else we can do to work around it. Or if anyone has experienced this problem, do you know if it's fixed in CF9?

Below is a stack trace.

Mylyn "focus on context" button gone from Navigator after Beta 3 update

forums_noreply@adobe.com — Mon, 04 Jan 2010 17:00:24 GMT

I use Mylyn/Foglyn with ColdFusion Builder Standalone on Vista. After updating my install this morning (reinstalled CFB and all plugins), the "focus on context" purple bubble button is gone from my Navigator panel, so I can no longer filter the navigator view to only show my current task context.

One coworker is on a Mac and it shows for him, but it seems to be gone for those of us on PCs.

Everything else in Mylyn/Foglyn works fine.

Does anyone have a solution to this?

Thanks!
