I am trying to do a summary backfill for the searches of my app, and it's failing.
It complains that an other backfill is still running ,but they are none (checked the processes)

"An instance of fill_summary_index is already running for app=myapp"

The problem was a lock files in my app.
Probably created by the previous run of the backfill that crashes.

I went to my app, and delete the file
$SPLUNK_HOME/etc/apps/myapp/log/fsidx*.log

Then I was able to run my backfill.
