Multisite Distributed Search: Why am I getting search head error "Encountered an error deserializing SearchResultsInfo from Results Stream header"?

Hi,

In a multisite distributed search environment with 1 search head and 4 indexers, it seems that the Search Head has difficulties to retrieve answers from the different indexers. Found this error in the search result of the search head :

ERROR SearchResultParserExecutor - Encountered an error deserializing SearchResultsInfo from ResultsStream header.

Anybody knows if it linked and how to fix it?
Splunk Entreprise 6.3.1

Hi,

Update :

We noticed that issue also happens when performing search on the _audit index !! As you can see below only 3 of the 4 indexers retreive informations

I found an open bug ticket with similar symptoms. Please open a case with Splunk support and provide a diag from your search head and at least one of your indexers.

Hi,

Case opened with Splunk on this issue. Indexers randomly missing when performing search form the SH on various index. It seems to be linked with this error, moreover we don't have it in the search.log when all indexers are displayed in the splunk-server field (i.e for a search with no problem).

Is this a bug? What is the SPL code? I am seeing these errors in a large environment I am currently working with. It is also running 6.3.1. Thanks. It appears to jam the search, then after a number of seconds it then continues and results are displayed.

Ditto, Saw it on an adhoc search and took too long to respond on the SHC.
