Why is the nodejs unable to perform a number of sequential queries?

[faustf]

Hi guys,

I have a nodejs service that needs to perform number of sequential queries:
e.g:

search mysearch from 01/01/2018 00:00:00 to 00:05:00
search mysearch from 01/01/2018 00:05:00 to 00:10:00
search mysearch from 01/01/2018 00:10:00 to 00:15:00
....
....
until 14/01/2018 00:00:00

The queries are very fast ( < 1s)

In my tests environment I have no problem (Splunk version 6.5.2)

In my production environment (Splunk version: 6.6.2), after some queries I receive an error:

[SPLUNKD] Unknown sid.
error: SplunkSearcher.search :: Error {"response":{"headers":{"date":"Mon, 05 Feb 2018 12:45:31 GMT","expires":"Thu, 26 Oct 1978 00:00:00 GMT","cache-control":"no-store, no-cache, must-revalidate, max-age=0","content-type":"application/json; charset=UTF-8","x-content-type-options":"nosniff","content-length":"53","vary":"Cookie, Authorization","connection":"Close","set-cookie":["splunkd_8089=jlHwfXrZZNgO.....; Path=/; Secure; HttpOnly; Max-Age=3600; Expires=Mon, 05 Feb 2018 13:45:31 GMT"],"x-frame-options":"SAMEORIGIN","server":"Splunkd"},"statusCode":404},"status":404,"data":{"messages":[{"type":"FATAL","text":"Unknown sid."}]},"error":null}

The nodejs service and the Splunk server are on the same server.

What could be the problem and how can I debug it?

thank you

Even I had similar issue when I was working with nodeJs...
But in a different environment.. CLient Browser + Server NodeJs(web component)..

In my issue the problem was not with node js... It was with the client browser.. Maximum concurrent session for a domain is 6...

May be your issue is also in the consumer part.. nodejs mostly works fine..
Try investigate on your consumer side as well...
It may queue your requests...
