Really sorry to hear that you're having trouble. Given the way that Indigo runs plugins (and the simple nature of this plugin in particular) I don't think the Announcements plugin is the cause of the server restart (anything is possible of course).

It sounds like your announcements file may have become corrupted. In thinking through the possible causes, it may be that the server restart occurred during a read/write operation, but that *should* only be possible if you were actively editing an Announcements device at the time of the restart. On your server machine, take a look at this file:

Code: Select all

/Library/Application Support/Perceptive Automation/Indigo X.X/Preferences/Plugins/com.fogbert.indigoplugin.announcements.txt


where X.X is your Indigo server version number.

Does that file seem corrupted? If you're not sure and are comfortable doing so, please feel free to copy and paste that file into a reply (or DM).

Do you have the ability to restore that file from a recent backup? That might be the easiest next step.

(Regardless, I will add some additional code to the plugin to allow it to fail more gracefully in such circumstances.)

Hi Dave,
I have used Timemachine to go back to an earlier backup with no success, still not working.

I found the file and it is empty 0 byte and no text at all, the file was updated yesterday morning.

I also checked earlier version of Indigo.
Version 2021.2 empty file (current version)
Version 2021.1 txt

Ok, if those prior backups are also "empty", it has been borked for a while. Hopefully, the following steps will work.

1. Stop the Announcements plugin.
2. Replace the Announcements.txt file that is "empty" (empty braces) with the last good version (the one you posted above). Be sure to use a plain text editor.
3. Restart the plugin.
4. Wait for it to run through a complete cycle (the time this takes will depend on your refresh settings). You may be able to select "Refresh Announcements" from the plugin menu.

This should refresh the devices to the last healthy state.

Thanks a lot Dave,

Followed your instructions and it is up and running again.

Glad to hear that worked.

Also a good reminder of how important it is to have backups!
