Few users getting Dispatch Error in dashboard but works fine in Adhoc searchs

[SathyaNarayanan]

Hi Splunkers,

Am having Admin privilege, when i run a query i dont get any errors in adhoc searches as well as dahboard , but few users when they run the query as adhoc search its works but in dashboard it showing the below error.

Dispatch dir=/opt/splunk/var/run/splunk/dispatch/subsearch_subsearch_subsearch_subsearch__ * does not exist anymore. Canceling search!

Any idea.

Thanks in advance
