  • The two page Files which are mentioned in the below log Error, they do not present on the CMS. 
  • When i try to execute the indexing job manually i see no error but when it happns automatically i see below errors and continuous outages. 
  • The Episerver version is Episerver CMS 7.0 and Episerver.Find.CMS  DLL version is 7.0.586.0

Automatic scheduled jobs are not executed on a web request. Therfore under Schedule Job, HttpContext.Current will be null, Indexing job will not have any user rights during run. The manual trigger will cause the task to run with the currently logged in user’s account and with access to that HttpContext. If you do not require those objects getting indexed, exclude them by using Find Conventions. Otherwise under the version you mentioned most probably you may require to build custom job to cover access issues in your scenario.

Hi Khan,

Thanks for responding back. I have 2 questions though.

1) how does these errors responsible to take the site down for  couple minutes? 

2) If you notice i see 400 bad request in the http unhandled exception. Does it because of the httpcpntext.currnt value is null?

  • Do you think it is because of the find.cms version i used in my application has some of the bugs? Does upgrading that solve this ?
  • Also regrading those page file IDs, they are no longer be part of the CMS therefore i am not sure of what page types they are. IS there any other way to exclude them from indexing if the pages are deleted or unpublished ?

Thanks,

Hiral

I am afraid, based on the exception, I cannot make any relation of site outages. After stopping this service, was your site working ok? There are hunderds of reasons (mostly memory leaks) I have seen, sometime just badly structured Top menu was the reason of these kind of periodic outages. In most of the cases EPiServer was very robust but custom logics effects performance.

Generally I will highly recommend to stay updated as updates contains not only new features but also fixes regarding performance and security. Updates doesn't guranties that your site issue will get resolved untill we know the reason. Have a look on release notes, may you find some hint.
