TMM will run out of memory If the issue persists. User will not be able to log in due to profile not found error similar to the following: err apmd[13681]: 01490114:3: /Common/workspace-acess2:Common:a6b495ce: process_request(): Profile '/Common/workspace-acess2' was not found
The issue happens if an access profile contains many resources, the resulting configuration snapshot will have even more configuration variables.
None.
APM policy configuration snapshot generation performance for very large configurations has been improved.
