bash-4.2$ pwd

bash-4.2$

Environment

Release : 10.6

Component : Service Virtualization

Cause

Cause:  cannot open ‘server.log’ for reading: Permission denied

Resolution

Looks like the permission on the log folder changed and IAM was not able to write the logs. Given Read/Write permission to the IAM/Standalone/log folder and IAM was able to start successfully.
