B4J Question Strange Repeating Error

[tufanv]

Hello,

I have a non-ui app that use httpjob every second to get some financial data and upload to my own server.
I am always getting the error at the same time when the error happens.. It happens every 3-4 days at 00.11.00 (eleven past zero ) . At very same second everytime.

I enabled logs with nohup this time and this is the error i get:

I need to understand what is the reson for this error. Is it from my side by the non-ui app or my server's problem or the remote server which i get the data so i can find a solution. Also when this error happens my timer does not try the next attempt the app just pauses. It does not crash ..

Also is there a way ,At least to continue with the next try when this happens ?

TY

You should expect requests to fail from time to time. Their server is probably offline at that point.

JobDone will be raised with Job.Success = False. You can continue to send requests.

Ok I will send another request in case of job fail and try that way this time. Thanks

Don't sent it immediately. Use CallSubPlus to send it again after 10 seconds.

you are talking about just in the if job.success=false section right ? to wait 10 second and start updates again ?
because i need to get the data every second for realtime updates.

Yes. You can make the interval shorter.
