The link works great, but I was wondering if there was a way to automate it. Especially for Panel Edition installs that may lose power… hypothetically speaking… not that it ever happens around here… ![:mrgreen:](https://us1.discourse-cdn.com/inductiveautomation/original/1X/d23659b203d2d24d394be983a52adb2fa6fe23d4.gif "Mr. Green") ---

Tiny little bump… OT: Have a great Memorial Day weekend with lots of time spent with family and friends and cooking things with fire… ![:mrgreen:](https://us1.discourse-cdn.com/inductiveautomation/original/1X/d23659b203d2d24d394be983a52adb2fa6fe23d4.gif "Mr. Green") ---

I’ve been playing with programming some modules, and I tried to do this using the Ignition Java API. I was able to find the sessions, and figure out which ones were stale. However, I didn’t find anything in the API that allows me to terminate a session using Java. In case I just missed something, here is the relevant code block. `for (ClientReqSession session : context.getGatewaySessionManager().findSessions()) { long timeSinceLastAccess = ((System.currentTimeMillis()-session.getLastAccessedTime())/1000); logger.info("Session last accessed "+timeSinceLastAccess+" seconds ago."); if (timeSinceLastAccess > 10) { // Kill the session } }` If there is a way to do a session.kill(), I’d be happy to throw that in and package this up as a module. ---

Thanks for taking a look at it, Kevin. I’ve had zero time for API/module development myself. I hate it when work gets in the way of the fun stuff… 😆 ---

It looks like my sessions actually have a Timeout value, that when it reaches that value, the session is automatically pruned. [localhost:8088/main/web/status/sessions](http://localhost:8088/main/web/status/sessions) (Running 7.2.6) ---

Well, yes. But, if we are only allowed 1 client session in panel edition and the client session isn’t flushed on startup from a power outage/flicker/flatulence, then I don’t really want to wait 10 minutes for it to automagically purge. I also have other machines that have to get back up and running, so I may not have time to manually purge them. I haven’t (yet) found where the timeout setpoints are kept, but if I can get it down a lot lower, then I can get my timing in in better shape to recover. On the flip side, I’ve noticed with panel edition that if it has an abandoned session, you can start a new one, and it works, but the autologon feature does not. Perhaps if that portion were looked at by IA, then the 10 minute limit may not be so bad. ---

Hey IA guys, is there any way to kill a session using the Module SDK? (See code earlier in the thread…) ---

Probably, but we generally don’t respond to general improvement requests with “write a module to code around it”. (Hint: see GatewaySessionManager in the Gateway API) Like Kevin said, client sessions are automatically pruned via the “timeout” mechanism. I think the real problem is that 10 minutes is way too long of a timeout, especially given than any live client will always ping the gateway every 2 seconds to make sure it’s still “connected”. Maybe changing the timeout to 1 minute would be an effective fix. ---

Still haven’t found out where this is set, but then, I’ve been off onto the the next crisis de jour. Is that floating somewhere in the ignition.conf file? EDIT: OK, maybe that wasn’t the right question to ask. I guess I’m asking “Is this something that’s user-configurable?”. Sorry, still tired from Father’s Day. Who said this was supposed to be a relaxing day?!? ---

Yeah, sorry to lead you on like that. This is a change we’d have to make in the software. Actually, I did end up making this change for 7.2.7. ---

Ah. 😮 That would explain why I couldn’t find anything. I’ll wait patiently. Thanks, Carl. Your hero status has been restored.
