Hello,

i'm having this issue that, after afew days that the system looks healthy, suddenly stops to be responsive, becomes impossible to reach the localhost website (from the same machine that is installed) and becomes impossible to start the client locally.

If i restart the machine the error fixes itself , then reappear after a couple of days..

The screenshots of the errors are here [Ignition Issue - Album on Imgur](https://imgur.com/a/QSv5n0L)

Edit: also becomes difficult to troubleshoot because i find this issue possibly many hours after the occurance, so the log files becomes huge and i'm not really sure what to look for.

This is the wrapper:

Looks like a socket leak. Are you using try-finally blocks around your socket code to ensure sockets are closed after use? Do you have to use urllib? (It has a bad reputation in jython.) If at all possible, convert your code to use the new httpClient functionality in v8.1.

Thank You Phil !

I will add try-catch and see if it fixes the issue the next time i can test this.

Sadly for this project has been decided to use already ignition 7.9 …

I dont know any other ways to send http commands, i’m new to python and java

Thanks again

Andrea

I would use java’s socket and URL classes instead of python, since Ignition uses **jython**.

Do you know where i can find any examples?  
My implementation now is made in the designer, this is my code at the moment:

1- on a 10 second script in the gateaway:

> import urllib2  
> value=system.tag.read("aps-e-ferry/Alarms/Record")  
> if value.value \> 0 :  
> intvalue = value.value - 10  
> system.tag.write("aps-e-ferry/Alarms/Record", intvalue)  
> else :  
> try:  
> req = urllib2.urlopen('[http://localhost:8090/command.cgi?oid=1&ot=2&cmd=recordStop](http://localhost:8090/command.cgi?oid=1&ot=2&cmd=recordStop)')  
> except Exception , e:  
> print e  
> finally:  
> req.close()

2- in the trigger event of afew tags.

> if initialChange==0 and currentValue \> 0 :  
> import urllib2  
> try:  
> req = urllib2.urlopen('[http://localhost:8090/command.cgi?oid=1&ot=2&cmd=record](http://localhost:8090/command.cgi?oid=1&ot=2&cmd=record)')  
> system.tag.write("aps-e-ferry/Alarms/Record", 70)  
> except Exception , e:  
> print e  
> finally:  
> req.close()

The goal is to send a request to another program locally that is managing video recording of a ip camera for 60ish seconds in case of allarm.

If you feel like there are better way to implement this keeping the code in the designer please share.

Thank you again for your time

Andrea
