Symptom

When starting any component of StackState, the log shows a message similar to the following:

/opt/stackstate/*/bin/*.sh: line 45: /opt/stackstate/var/log/*/*.log: Permission denied

Cause

StackState has been started using root or other user credentials followed by starting StackState as a service.

Solution

Remove the contents of /opt/stackstate/var/log/stackstate and /opt/stackstate/var/log/stackgraph directories and restart StackState.
