apmd process cannot start correctly and restarts in an infinite loop. When apmd initializes the Allow Ending agent, the process tries to load all resources (including ACLs, the webtop, and all resources for every webtop, app tunnels, rdp, etc.). The most likely configuration to encounter this issue is with ACLs. For example, if you have thousands of ACL records, the Allow agent pulls them all at once. If the mcpd process is consumed with other operations, it might be that apmd cannot initialize the Allow agent in 30 secs, so it restarts, at which point the process tries to load all resources, cannot complete within the 30 seconds, and restarts in a loop.
APM end users cannot authenticate.
Too many resources assigned in an Access Policy profile for example thousands of ACLs configured. apmd cannot initialize the Allow Ending agent in 30 seconds and decides it has stopped responding. Then it restarts by it's own, but problem is not solved, so it restarts in a loop
Reduce amount of resources so every agent can initialize within the 30-second timeframe.
