In /opt/splunk/var/run/splunk/distach --In this path i cleared the cache file and restarted search head

But in some case after restarting i will get same error .but i tried in some other browser (internet explorer) the search is working fine

Hey @karthi2809, if @koshyk answered your question, please remember to "√Accept" the answer to award karma points and to let other Splunkers know there’s a working solution. We’re hosting a karma point contest, so it’s particularly awesome to up vote on Answers these days. 😄

The reason is your filesystem (or disk) which the /opt/splunk/var/run is installed is less than the minimum specified in your server.conf Make it to say 500MB or smaller value.

 [diskUsage]
 minFreeSpace = <num>

Or edit via UI,

Settings -> Server settings » General settings -> Pause indexing if free disk space (in MB) falls below *

But DO NOT do this for real environment. In PROD clustered Search Head, it should have 50GB of installation due to huge bundles etc. STandalone SH should be in 10GB minimum for practical purposes
