We have upgraded site from sitecore 8.0 rev.150223 (8.0 Update-2) to Sitecore 8.2 rev. 170614 (8.2 Update-4). This is content heavy site. When I Publish individual nodes, there is no problem in publishing but when we hit Publish Site, after 4500000 items published we are getting error and publishing stop there.

Getting this error -

Anyone has any idea?

  • About how long into the publish is it taking until this error occurs? Dec 11, 2017 at 18:15
  • 5-6 hours around.. Dec 11, 2017 at 18:20

    I recommend you explore the option of the Sitecore Publishing Service which is supported for your version. The publishing is performed in batches and should dramatically reduce the publishing time. Well below the 5 hour mark for sure. Dec 11, 2017 at 18:43
  • Yeah I want to try that..but we can not use it right now. That's why looking for other options. Dec 11, 2017 at 18:51
  • What type of publishing are you performing? If you are using incremental publish and this is taking 5 hours or more, i would recommend to clear the publish queue table and perform publish in batch. Dec 11, 2017 at 19:59

I think you question has two aspects which need to be handled separately:

1- Publish failing after a period of time

2- The slowness and time it takes to perform a full publish.

Publish failing after a period of time

The reason why it fails can be for many reasons most likely one item is corrupted or requesting something that it can't find, for example a required language it can't find, or a custom event handler being called which is throwing an exception, or anything really. To make your life easier you can have a clean Sitecore 8.2 rev. 170614 site running and compare the publish configurations against yours on the showconfig page. This will help you figure out whether you have any custom events running that may be leading to the exception or pinpoint possible causes.

The slowness and time it takes to perform a full publish

As already suggesed on comments Sitecore has released a publishing service which comes with a module that can be used and helps scaling the publishing mechanism. This currently is not an out-of-the-box module but it does work well. If you use it you need to understand that now your Sitecore instance will use that publishing service to run any publishing as opposed to the out-of-the-box. It also requires a few things like .Net core. This module is really good if you need to perform distributed publishing as well.

  • Yeah but we can not use publishing service for now as we didn't get green signal from client on it. When I am publishing in batches that works for me but again when I publishing whole site then getting error. Dec 13, 2017 at 16:33
  • have you checked for custom events running on publishing?

  • Yes, I have disabled those and then tried. Dec 13, 2017 at 16:41

You can make use of the Sitecore Publishing Module. This will takes less than 5 hours to publish. But as you mentioned in the comment above, you cannot use the publishing service right now.

Possible solution

Since you just did an upgrade, sitecore will identify all the items to be published. If you are performing an incremental publish and still taking too much time and at the end crashed, try the following steps:

  1. Clear the publish queue table on master core and web.

  2. Perform publishing in batches

Once done, try to launch an incremental publish again. This should now takes less time.

  • I have already cleared publishqueue, eventqueue for all databases and also published in batches but after these when I am doing incremental site publish I am still getting error. Dec 13, 2017 at 16:31
