Scheduled Publish
That post is very old. I'm pretty sure that all builtin scheduled jobs have been moved to ISychronizedObjectInstanceCache now, which works across servers. It seems the problem is something else ...

Well thats good and explains why I hadn't noticed it before. Any ideas where I should look for the issue. I don't seem to be able to find any related errors anywhere.

Can't say for sure because it seems the problem is with your site configuration. If you edit a page (manually) on one server, do other servers get updated correctly?

Yep, everything works fine aside from delayed scheduled jobs. Also sometimes the scheduled job says nothing published even though it has published some of it. So I think something is crashing somewhere.

@quan I am using Episer ver 9.8.2 , I tried to create my own public class DelayedPublishJob : ScheduledJobBase to try and add some debug code but it uses internal contentrepository. Is it possible to do this?

Also we have the timeout set to a minute. What would happen if it was still processing the last changes. I can't see that the code handles that.

So it seems it worked before and then stop working recently? You didnot mention if you are running on Azure or not, but you should go check the UDP setting (for on-premise) or Azure Events setting (for Azure). It sounds like if you run the job every minute it might send too many cache validation "events" across network that might have stuck somewhere

interesting would be also to see Remote Event page screenshot from Episerver DeveloperTools.

Hey,
We are using Amazon SQS. I checked and all the SQS queues were low. Even though the job runs every minute, scheduled work is normally in batches and we are not using projects. Is the remote events an Episerver Hosted thing?
Oct 17, 2018 16:57
I appear to be confused or the fact we are on page two and the forum has displayed my initial message again has confused Quan. Validis suggests there is page that displays the remote events. Is that a thing? I haven't found this, we use SQS and I have been monitoring the length of the queues from Amazon.

No I was answering your question, remote events are not a "Episerver hosted" thing. it uses the mechanism provided by the environment (WCF UDP, Azure Events or Amazon SQS - which I'm pretty clueless about)
Oct 17, 2018 20:06
ok, so yes we have remote events setup correctly and have been running for some time.
In resposne to your statement:
"It sounds like if you run the job every minute it might send too many cache validation "events" across network that might have stuck somewhere "
I don't believe this is the case as the SQS queue lengths in Amazon were empty and we don't normally have items scheduled for 4:01, 4:02, we normally schedule a lot of work for 4:00 and then there is not normally anything more for an hour. We wanted the delay publish on 1 minute so we actually publish the work when the editor decides and not x amount of minues after.
In response to:
"So it seems it worked before and then stop working recently?"
Yes this is true, it randomly stopped working on Tuesday. We increased the delay from 1 minute to 5 minutes and the problem seems to have vanished.

Does this mean there is a page somewhere in Episerver that shows me the remote events status on the server?

was referrring to Episerver DevTools nuget pacakge. it has some interesting statistics around remote events.
Oct 17, 2018 21:44
Hey,
Thanks for that. I am afraid looking at https://nuget.episerver.com/package?id=EPiServer.DeveloperTools&v=2.1.0 I can not install as our CMS version is currently too low.

Adam,
Note that several versions of that package are available. As you select a version, its list of Dependencies changes.

the lowest available is for Episerver 7.5 - https://github.com/episerver/DeveloperTools/releases/tag/v1.1.0

Hey,
I have a few bits of advice:
- Ensure the scheduler is only running on one machine. (https://world.episerver.com/forum/developer-forum/-Episerver-75-CMS/Thread-Container/2014/11/disable-schedule-jobs-on-a-specific-server-in-a-load-balanced-environment/)
- Ensure that machine is pushing notifications to the other machines to invalidate the cache. (https://world.episerver.com/documentation/Items/Developers-Guide/Episerver-CMS/75/Event-management/Event-management/)
- Ensure you don't have a rouge machine processing those jobs.
I hope that helps.

Hey,
Recently my schedule publish has just stopped working. Sometimes it invalidates on remote servers but the current server hasn't been invalidated and some of the post publish code hadn't completed running. Looking at http://joelabrahamsson.com/how-episerver-cms-caches-pagedata-objects/ and other pages, they suggest that EpiServer delayed publish does not invalidate the cache on the other servers. Is this correct? and if so does anyone know why?
