I am not able to use Service management from adminui, It says service was .MarkedForRollbackException: The current transaction has been marked for rollback. I dont know why this error is coming, Please let me know how this can be resolved.
Is this happening for a specific service, which you are looking into from adminui > Application and Services > Service Management ?
Please share the log snippet of that time , when you try to use Service management.
Additionally, if it is a specific service > please try once, stopping ans starting that service from Workbench > Components tab section. ( Share the server log snippet in case of failure)
