Components Used
The information in this document is based on CloudCenter version 4.x.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
Background Information
When you try to save an application profile, the user receives an error in UI:
"Could not save topology: Unable to save the content in the repository (possibly a version loop)".
Problem
In UI, the user receives this error:
"Could not save topology: Unable to save the content in the repository (possibly a version loop)".
Error found in CCM osmosix.log:
VENDOR_ID::1::USER_ID::2::2016-10-05 20:35:32,923 ERROR impl.DistributedJobTemplateRepositoryImpl [http-apr-10443-exec-6] - Unable to save the content in the repository.

com.osmosix.commons.exception.CliqrApplicationException: Unable to save the content in the repository (possibly a version loop).
Solution
1. Login to CloudCenter Manager (CCM) via Secure Shell (SSH).
2. Remove these two folders:
- /tmp/repository
- /tmp/hsperfdata_<userid>
3. Restart Tomcat service:
- /etc/init.d/tomcat stop
- /etc/init.d/tomcat start
