Script killed

[jaymc]

Hey, Im running an php msn bot

 

My problem is that it loses connection after around 20 seconds. I have spoke with the developer of this and he says it works fine on 90% of servers

 

He has advised that the script is being terminated by the OS / php

 

My question is, what has the power to automatically kill a php script. I have checked php.ini and things such as max_execution_time , set_time_limit are both 10 minutes

 

What other settings control when and if to terminate a php script that it thinks has been running too long

20 seconds is a lot for a webpage. I don't know the exact timeout of browser but some will eventually report a timeout if your expect your script to run for more than 20 seconds. I don't think most visitor will wait that long.

 

If your building a bot or want to run a background job you should check for a cron job instead. Just ask google about crontab/cron job you will find a lot of ressource on how to set a job to run on background at regular interval.

 

I don't know about your environement at all but some shared hosting may have installed something to shut the script after some time. Or it may be the memory requirement that kill the script.

if your on window, open the command line...

 

and type:

 

php C:\bot.php

 

change C:\bot.php to your bot's location

 

see how long it runs in there

Hi

 

Thanks for answers

 

Im running it via ssh php -q bot.php

 

Its my server not a shared host. All enviroment variables such as memory, execution time are more than adequate

 

Any other ideas?

How is the bot connecting? If its via fsockopen() then you can specify the timeout as a parameter. You may also need to look at stream_set_timeout(). It's possible that your router could be dropping the connection or possibly firewall.

[jaymc]

I have tried it on two different servers

 

One which is behind my own router

another which is in a datacenter

 

Both get killed after 15 seconds, tried with firewall off too

 

Yes it does use fsocket but isnt setting the timeout based on if it cant get a connection as apposed to keeping it running for more than 15 seconds?

[JonnoTheDev]

Both get killed after 15 seconds, tried with firewall off too

Then how do you know if it is not the remote end terminating the connection as opposed to the client.

set_time_limit

 

Have you tried increasing the timeout limit of PHP. Chances are PHP is just timing out after the normal time like it is suppose to.

Still sounds like a php.ini problem.

 

Most distributions have 2 php.ini's. One is for the web and the other one is for the cli. Make sure you're looking at the php.ini for the cli.

[jaymc]

I only have one php.ini file

 

Here are the key settings

 

;;;;;;;;;;;;;;;;;;;
; Resource Limits ;
;;;;;;;;;;;;;;;;;;;
max_execution_time = 3600     ; Maximum execution time of each script, in seconds
max_input_time = 6000   ; Maximum amount of time each script may spend parsing request data
memory_limit = 3024M      ; Maximum amount of memory a script may consume (16MB)

; Default timeout for socket based streams (seconds)
default_socket_timeout = 3600

; Maximum size of POST data that PHP will accept.
post_max_size = 2048M

; Maximum allowed size for uploaded files.
upload_max_filesize = 2048M

 

I have also tried running it from the browser as apposed to ssh

Any more ideas?

I checked ps aux and its hardly using any RAM or CPU, not to mention the machine has 5GB of ram anyway

[keeB]

Can you please post any errors that happen?

[jaymc]

Hi

 

There are no errors. The msn bot will function perfectly but goes offline after 20-30 seconds. When that happens it is no longer in ps aux

 

The guy who made it said he has heard of this issue from other people who use the bot but assures it works fine on systems he has tested which include windows/linux

 

Hence, he believes enviroment issue such as php.ini setting / operating setting

[keeB]

You're sure there are no errors?

 

So you run:

 

php bot.php

 

And in the end it just terminates without printing anything?

[jaymc]

Correct

 

The bot signs into msn, stays online for 20 seconds

 

If you send it messages it will function as expected as in return messages back to you

 

Strangely, by talking to it this causes it to stay online, until you stop talking

 

Perhaps because the socket is active

 

But no errors, just a general timeout kind of thing when there is no communication to the bot from an msn user

[keeB]

I bet what's happening is there's a timeout from MSN on the socket. Clasically, In order to keep a socket alive you need to send a NOOP (or similar.)

 

I think the extensive testing the author told you about was on a really active bot

[jaymc]

The developer has just signed the bot in his side and it stayed online

 

Bare in mind the only person on its contact list is me and of course I did not speak to it..

The fact that you're not getting an error is what's troubling me still. Are you familiar with XDebug? If you could run it through the debugger to find out where it's exiting it could give more information.
