Task scheduler hung up and stopped completing tasks for several days

Hi,

Maybe you should check the Handling Hung Routines option in the task editing page (Dashboard -> Task Scheduler -> Tasks -> Edit (of your choosing task) ).

Hope this helps.

Thanks, that resolved the issue ??

Great!

Would be appreciated if you could take a few minutes to write a review about this plugin. Thank you!

Actually it’s still not fixed ?? The tasks are getting hung up and then the tasks assigned to delete the old tasks are getting hung up. Also it looks like all of the tasks since one of these issues are timing out and getting deleted without completing.
What else can I do to resolve this? The client is unhappy as this is the second week it hasn’t been working properly.

What settings would you recommend to resolve this? Currently have it set as:

Interval:
every 2 minutes

Max count of log entries: 0
Max Task Execution Time: 30 seconds
Execute the action even when the last routine is not completed.
Handling Hung Routines: Terminate and remove the routine.

I was thinking of increasing the interval to 10 minutes, and also the max execution time to 9 minutes in the hopes that will give the script enough time to run. Does this make sense? Anything else I can try to make this reliable?

Hmm,

Indeed you should definitely try increasing the interval and the max execution time. Let’s see how it goes. If that fails, there will be nothing more you can try actually. In that case, I have to reproduce the problem on my end to examine what the real cause is so you need to tell me the steps to reproduce it.

OK I increased the execution time and it was fine for a while, but 5 days ago it hung up and just kept timing out tasks for the last 5 days ?? After I cleared out all the hung tasks and ran it again it worked correctly. What can I do at this point to make sure it works reliably? If anything?

It looks like once two instances of the automated tasks designed to clear out hung tasks themselves get hung, the whole thing grinds to a halt. Is there a way to just automatically clear out all tasks once an hour or something like that?

Here’s how I have it set now. Is this optimized for reliability, or would other settings work better?

Server heartbeat: 24 seconds

Max number of background routines: 12

Max count of log entries – 0

Max task execution time – 300

Another thing that would be useful is some way to generate an email if the tasks get hung for more than an hour or so. That way at least I would know it was happening.

Hi,

I’ve posted a small plugin that periodically checks hung routines and deletes them. So you should try it. There is a download link in the page.

And modify the following values to suit your needs.

    public $iElapsedTime    = 1800; // seconds - 30 minutes
    public $iCheckInterval  = 43200; // seconds - 12 hours

$iElapsedTime should holds the elapsed time duration from the routine is started. iCheckInterval determines how often the check is performed.

Hope this helps.

Awesome! Thanks so much! I’ve installed the new plugin. I’ll let you know how it goes.
