    7.3.5 Deadlock, umbracoServer query

    bugs
    Umbraco 7

    I'm having a recurring deadlock issue with a site running multiple instances on Azure. The offending query is:

    SELECT [umbracoServer].[id], [umbracoServer].[address], [umbracoServer].[computerName], [umbracoServer].[registeredDate], [umbracoServer].[lastNotifiedDate], [umbracoServer].[isActive], [umbracoServer].[isMaster] FROM [umbracoServer] WHERE id > 0

    Site is running 7.3.5 on latest Azure database, SQL 2016.

    The Umbraco configuration is pretty much standard with only 1 change in the web.config:

    <add key="umbracoContentXMLUseLocalTemp" value="false" />

    Any help would be appreciated!

    We have the same issue in Umbraco 7.3.4 on a load balancing server - not Azure.

    Did you find the reason/solution?

    We are getting about 3 or 4 deadlocks a minute. They are all around the umbracoServer table, where multiple processes are trying to update this table.

    Thanks in advance

    Hi Anz,

    Your set-up sounds the same as mine... Did you ever manage to fix this?

    If you are still stuck, here's what I've found out, as minimal as it is (and without any solution):

    Currently we only get these deadlocks in 7.3.4 - other versions we've used are ok (so far).

    The UmbracoTraceLog has entries which match the reported deadlock times, and mentions:

    ERROR Umbraco.Core.Persistence.UmbracoDatabase - Database exception occurred

    and

    ERROR Umbraco.Web.Strategies.ServerRegistrationEventHandler - Failed to update server record in database.

    I'm wondering if upgrading Umbraco would be the only way to fix this, but I'd need reassurance from Umbraco HQ that it would before I do anything.

    Good luck if you're still stuck with this issue too...!

    UPDATE: This has now started happening on a 7.3.3 and 7.3.6 site too.

    Has this issue been addressed anywhere, does anybody know?

    Same issue for me on 7.3.3, 7.3.4 and 7.3.6 load balanced servers.

    In the absence of any news I've raised a bug here.

    Hi Gordon and all,

    I am meeting this problem too with Umbraco 7.3.1.

    Do you have any workaround solution to overcome this ?

    Hi

    I've not found a solution to this, despite a lot of digging about... If you ever find anything do let us know. I don't know if newer versions of Umbraco have addressed this problem or not - is this issue being ignored by the Umbraco team?

    Thanks

    Has this ever been resolved?

    I've upgraded to 776 and am now getting the same issue. Site has been running for a year on Azure. Now with the upgrade we are receiving deadlock info in the admin panel.

    Umbraco.Web.Strategies.ServerRegistrationEventHandler - Failed to update server record in database.
