    Publishing or deleting item in the umbraco backoffice times out


    We are currently experiencing issues on a umbraco 7.5.13 site. After a couple hours the umbraco backoffice becomes very slow and actions like publishing or deleting a document takes forever or times out, then we have to recycle the apppool to make it work again.

    The live site is still ok.

    In the logs this is the only error that pops up:

    Umbraco.Core.Sync.DatabaseServerMessenger - DISTRIBUTED CACHE IS NOT UPDATED. Failed to execute instructions (id: 28972, instruction count: 1). Instruction is being skipped/ignored The thread has been aborted, because the request has timed out.

    Any ideas on where to look?

    Thanks in advance.

    Hi Arne,

    I've heard of this kind of thing happening in older versions of Umbraco where content editors publish a large amount of nodes in one go (issues occur due to instructions being processed on a request thread) or where a site has been incorrectly configured for its environment.

    Is this site load balanced? If so, have you followed the instructions here: There are number of config changes required for the XML cache file, temp files and examine to function correctly in a load balanced environment.

    Shannon from Umbraco HQ previously gave the below advice for folk experiencing the errror you mentioned:

    • Make sure you are running on the latest version of Umbraco
    • If you want to cold boot your site, delete the App_Data/TEMP/DistCache folder and restart the site - this will bypass all instructions and reset your site to the latest
    • Try to update the executionTimeout since instructions are processed in a request thread currently and this is why the 'thread was being aborted' exception appears

    Some helpful issues threads:

    Hi Andy,

    Thanks for taking the time to reply.

    The site is not load balanced.

    I will try to delete the cache folder and update the executionTimeout.

    Kind regards,
