Hi Support,

I have a product issue to report that exists in the DefaultContentLanguageSettingsHandler.GetContentLanguageSetting method. This is being identified using the Briscoe client.

The current method uses a local within a lambda and this causes a function to be allocated for every execution and, given the hit count of this method, that’s a lot of memory (just a little shy of 1GB within 130 seconds).

So, in this particular case it’s better to iterate through the enumerable.

private static ContentLanguageSetting GetContentLanguageSetting(IEnumerable<ContentLanguageSetting> languageSettings, string languageBranch)


foreach (var languageSetting in languageSettings)


if (string.Equals(languageSetting.LanguageBranch, languageBranch, StringComparison.OrdinalIgnoreCase))

{ return languageSetting; }


return null;


The above code is the fix.

* Please see Zendesk Support tab for further comments and attachments.

Note for QA: To verify this we should make sure LanguageSettings (fallback/replacement) still work work as previously.
