Managed server didn't initialize after X ms.The startup time limit might be restrictive and cause downtime in environments affected by high CPU usage and memory consumption.
Upgrade to 20.10.5+ to increase the startup time limit to 300 seconds.
If this is insufficient, it means that the server is attempting to execute something, and has a deadlock. This is usually

EnableMigrations parameter is set to True, and there is a large migration hanging the main thread.
If the flag is set to
False, collect a memory dump, and submit it to your customer representative.
