Are you using the API to create session keys and logging in players from a web site? Are you getting errors in the error log related to these duplicates?

FWIW, even if that were true, it would still flag an execution issue on the PM side as the session key generation, login maintenance, etc., are all PM-managed.

However, the multiple logins do not appear to be generated by multiple login attempts through the front-end, i.e., people are not logging out / getting booted and then retrying. Instead, the server begins failing to respond and a side effect we've noticed is that multiple logins are suddenly listed for some (all?) users. In this case, they've never left PM to return to the front-end experience for login.

Further, when a user does attempt to login through the front-end experience while connected to PM through a session previously created (e.g., in a different tab or on a different device), the older session for their account is automatically disconnected by PM, which means they are not able to connect through two different sessions simultaneously.

Kent: Yes, that's the flow. No, we get no errors. See the response to ftpjesus' post RE multiple session keys. In short, PM handles this directly and correctly.

True, and I think I've got that part fixed even though I still don't know how it's getting duplicate login requests all at once.

Still having issues. It is just about every day now. Any progress?

I should have an update ready in the next day or two.

We are now seeing almost nightly crashes. About half of the time, the server will eventually "recover", i.e., begin responding again. The other half, we are still needing to bounce the service to clear it. Needless to say, our players are very frustrated and we're at risk of losing them en masse.

While we would like to continue trying to provide analysis and debugging info, we're now at an inflection point as the crashes are making our site unsustainable, literally jeopardizing our entire player population. To that end, a couple of questions:
  • Do you have any additional insights or is there anything more we can provide?
  • Do you have any ideas on how we could potentially mitigate this in the interim? We are already bouncing the service once every day, which seemed to be helping until the latest minor release.
  • Is it possible to roll back to a previous version of the software? While we'd hate to lose some of the new features, we were not seeing this behavior with v6.

Are these crashes happening at your peak load times? Unless there are code exceptions in the error log you may just be overloading your server with more players or bandwidth than it can handle. Doubtful going back to v6 will help you but there are export/import features built into the Accounts tab.

  • Our peak loads are the same now as they were with v6. The crashes began with the major version release.
  • The crashes are not obviously tied to surges of traffic as they usually come well into the evening when players have been playing for some time, which understandably increases their frustration.
  • We run on AWS -- the monitors for the EC2 instance show no critical stress on the system at the time of the crashes (e.g., 7% of CPU).
  • The instance itself remains responsive -- only the Mavens software becomes unresponsive. We connect to the instance via Remote Desktop and bounce the service using your Service Manager, which almost always requires a "Force Close" when the service has become unresponsive.
