Puzzling schedule lapse

[Reddog99]

 I"ve delayed reporting this until I recognized a pattern: My weather station is set to download it's data to the computer hard drive every half-hour.  I have Yummy scheduled to upload 2 minutes later, every 30 minutes (09:02, 09:32, etc.). But Yummy has stopped uploading the data to my web site after the 15:32 update every day.

I've examined the log files, but they're mostly Greek to me. The weather station is still refreshing the files in the upload folder (new dates & times), and Yummy appears to go thru the motions, but updates zero files after 15:32. If I reset the schedule, Yummy will work until after the 15:32 update the next day. Have I got some setting wrong?

That's really odd, and something I've never had reported before.

I'm wondering if maybe there is a time zone difference between your Mac and your web site, and maybe this is coming into play here. Before you create and run your schedule next time, make sure you have the 'Automatically detect time offset' checkbox enabled and see if that makes any difference. Even if you think there shouldn't be a time zone difference, it won't hurt to enable this feature.

What exactly do you do when you 'reset the schedule'? Do you mean you re-configure the schedule, or do you completely cancel the synchronization and re-create it from scratch?

I'll see if I can reproduce this problem here in the meantime while I wait for your reply.

'Automatically detect time offset'  is (and has been) checked.

I'm not sure if the "Hiding" has any effect (I have Yummy hidden while the computer is running), but after the uploads stopped today, I un-hide the app... It didn't restart the uploads.

To "wake up" Yummy today, I only selected the files in the Mac side of the browser & dragged them to the server side. They got uploaded and then the schedule functioned normally at the next scheduled upload.

Yesterday, I diddled with the schedule. I probably played with all the settings. The problem there is that there doesn't appear to be any way to look at all the schedule settings once they have been made. Clicking on Synchronize just starts a new schedule, from what I can see.

Info I forgot to include in the first post:
Computer: G5-Quad
OS: 10.4.5 w/latest updates

For whatever it's worth, the website is http://users.wildblue.net/patrickward/

I'm going to try to attach the FTP transcript (zipped).

Thanks for the further information.

Although I can't be sure yet (I have to do more testing) I think there might be a certain time of day where synchronization is failing to notice changes, and this is related to the fact that the server is 8 hours ahead of you. The 16:02 update is the one where the sync is failing, and it just so happens that 8 hours ahead of this makes the server time as being the following day.

To see if this theory is correct, please leave Yummy running after the failure time to see if it starts uploading again at the one of the next updates.

Additionally, since the FTP Transcript is very useful, please select the 'Enable diagnostics' checkbox in your Synchronize options window. When the failure occurs, I'd like to see the transcript again. The diagnostics output included in the transcript will be useful.

As a side note, to adjust an existing schedule, simply click on the scheduled sync item in the queue drawer, then click the clock icon. This will show the schedule already set up.

Thanks!

Yummy has been getting stuck while I'm at work, so it's been NOT uploading until I get home at midnight. I'll let it keep trying after midnight tonight.

please select the 'Enable diagnostics' checkbox in your Synchronize options window.

'Enable diagnostics' checked. I assume this will add output to the same transcript?

As a side note, to adjust an existing schedule, simply click on the scheduled sync item in the queue drawer, then click the clock icon. This will show the schedule already set up.

This is exactly what I mean: the clock icon lets me adjust the schedule, but not see or change anything else. To Enable diagnostics, I had to create a new scheduled sync. To know what the 'other' settings are, I need to rely on my memory (an iffy proposition, at best). Clicking the Schedule icon only shows what was used last. If there is more than one schedule, or I want to change something about the scheduled sync I already have, I'm out of luck.... Or an I missing something?

Thanks for doing those tests, Pat!

You're right, the transcript will contain extra output when the diagnostics mode is enabled. It writes out the decisions that the syncrhonization engine made as to why a file should or should not be transferred, quoting the date, time and size of each. So, it's quite useful

You're mostly right about the Clock icon - it doesn't let you adjust the Synchronization properties, but only the schedule. However, you can have several differently scheduled synchronizations and/or transfers present in the queue drawer and still re-configure the schedule of each of them individually. I'll see if I can address the issue of adjustments to the Sync itself in an update, though, since this is certainly a deficiency.

I look forward to your results.

I came home tonight and didn't get to look at the computer until after midnight. The web site had stopped being updated earlier today, but at midnight the site was being updated when I looked. So my previous actions of doing a manual update may have had nothing to do with "waking" Yummy? At this point I'm not sure of anything.

The latest version of the log is attached.

Thank you for the transcript - with this evidence I am almost certain I know what the problem is. The 'waking' Yummy phenomenon certainly is a complete red herring.

Two things you can try to resolve this problem:

1) Enable the checkbox named 'Validate suspect file datestamps' in the Server options tab of the Preferences.
2) Although I am fairly confident that it will, if option 1 does not fix the problem, contact me via email to obtain the latest build of Yummy FTP. support at yummysoftware dot com

Thanks for being so patient!
