The workaround is to disable health reporting in health.conf (until the Bug is fixed in Splunk 7.2.x).

The issue is a known and is caused by the Bugs below.

SPL-162549
splunkweb fails to start and SHC member shows as down
Affects: 7.1.4
Fixed in: 7.1.6

SPL-160230
Splunkd web fails to start due to deadlock among Health Reporter threads
Affects: 7.1.2
Fixed in: 7.1.6

  1. Make the changes to the file below:

/etc/system/local/health.conf
