A lot of Clients with Solution <none>

[jcompagner]

yes there specific lock ups are fixed.

[merijnp]

What happens when I update, it updates to 6. Or is there also a release of 5.2 available? Because a lot changed in 6...

[jcompagner]

for 5.2 you need to wait for the next release (5.2.10), there is no release yet with that fix.

[merijnp]

Any idea when we can expect that 5.2.10 ? Because now I have to restart 2/3 times a day for the customer. Also in the weekend.

[jcompagner]

I can't believe that the bug that is fixed will cause that you have to restart that often. That can only happens once or twice because of some specific threading.
How many do you see hanging then just before you have to restart?
Because the thing i did see in your stackdump where only 1 to max 3 clients that where hanging. Not more.

[merijnp]

I restarted Servoy Application Server yesterday evening. And today I restarted just after 12:00. Today I had 135 clients in Servoy using solution Webshop. A few minutes after the restart about 14 clients logged in, about 14 clients is normal.

[jcompagner]

and those clients are just loaded an showing under the solution "webshop" ?

are you sure that all those webclients did close there browsers and then 30+ minutes later they are still there on the server?

[merijnp]

Yes they are just loaded and showing under the solution webshop.

- Our timeout is set to 1. So when the webclients close the browser, the webclient should disappear after 1 minute.
- Webclients can also use a logout button in the solution. When they use the button, we call application.exit(); This morning I checked one of the webclients that was still active. This user did use the button to logout.
- Clientside we also check the actions of our users. When they are not active 30+, we also use application.exit(); to throw them out.

[merijnp]

Hi Johan. We try to close idle clients using the following code. But after the application.exit(); the solution runs the scheduled job checkConnectionErrors for that client (and the client still is active). We try to stop this by adding removeAllScheduledJobs() but this doesn't work. It shouldn't be possible that a job starts after application.exit(); ?

Code: Select all

function CheckActivity()
{
                var _lastActivity = globals.LastActivity;
                var _currentdate = new Date();

                var _interval = globals.getSystemSetting("axerrio.idleclienttimeout");

                if(_interval!= null && _interval != "" && _interval > 0)
                {             
                               var _difference = plugins.it2be_tools.dateDifference(_currentdate,_lastActivity,3);
                               
                               if(_difference > _interval)
                               {
                                               //logout the user
                                               if(globals.logOffReturnUrl)
                                               {
                                                               //application.showURL(globals.logOffReturnUrl, "_self");
                                                               application.showURL(globals.logOffReturnUrl, "_top");
                                               }

                                               //security.logout();
                                               removeAllScheduledJobs();
                                               application.exit();
                               }
                }
               
}



/**
* @properties={typeid:24,uuid:"F026BD97-AFF3-4006-A7A7-B15B4EBD5AC0"}
*/

function removeAllScheduledJobs()
{
/*           var _jobs = plugins.scheduler.getCurrentJobNames();
                for (var i = 0; i < _jobs.length; i++)
                {
                               plugins.scheduler.removeJob(_jobs[i]);
                }
*/

                plugins.scheduler.removeJob("checkShoppingTime" + globals_to_webuser.login);
                plugins.scheduler.removeJob("checkReservationTime" + globals_to_webuser.login);
                plugins.scheduler.removeJob("checkShopOpen" + globals_to_webuser.login);
                plugins.scheduler.removeJob("checkConnectionErrors" + globals_to_webuser.login);
                plugins.scheduler.removeJob("checkIdleTime" + globals_to_webuser.login);
}

[jcompagner]

all those removes is already done by us, Servoy will delete the job's when a exit/shutdown/solution close happens.

But maybe because the exit somehow hangs it doesn't come that far, but that is only for clients where that deadlock when shutting down.

Besides that when a scheduler job would execute we still check if the client has the solution loaded before it can execute.
And the solution should be gone when you call close/shutdown

[merijnp]

After a shutdown the client is not removed from the list in Servoy Server Administration > Clients, the client is still active on Solution: Webshop.
We get this error a lot in our logs:

[jcompagner]

those first null pointers are quite strange.
How fast do the schedulers call methods?

because in the MethodExecutor.run() method:

at com.servoy.j2db.plugins.ClientPluginAccessProvider$MethodExecutor.run(ClientPluginAccessProvider.java:548)


we ask for the form, make sure it is in a consistent state, then call executeFunction:

at com.servoy.j2db.FormController.executeFunction(FormController.java:3841)

and there the form is already destroyed.. thats in time a split second later..

I will see if i can make that a bit more safe, but for now i guess the best thing to do is really make sure all jobs are destroyed before you call shutdown

I also see a few socket reset method coming from the database, those are also quite weird, you should check them.

[merijnp]

Our shortest scheduled job runs every five seconds.

We tried to destroy all jobs before we call the shutdown with our function removeAllScheduledJobs(),
but this doesn't work. It still calls the other scheduled job (which should be gone).

We have a lot of these socket resets, I think we need more error handling,
because in the Servoy Server Log I cannot see which database or solution while we have 23 database servers,
7 solutions and 3 batch processors.

[jcompagner]

i see you have 5 jobs running but what are all those times? if 1 is 5 seconds the other 7 another 9 and so on then a lot of jobs can happen at certain times.

And you can call removeJobs but there just can be 1 or 2 already in execute mode...

I guess what you can do is call removeJobs and then schedule a 1 time job that does the close/shutdown in lets say 15 seconds from now.

so give them all a bit more time to really shutdown

I will add a boolean for the return type of scheduler.removeJob() so that you can check if it worked according to the scheduler.

We made some changes in our code (at logout), now the server is running without problems for 1 day and 22 hours. Hope this solved the problem completely!
