Plugin stops running after a while

When you turn on debug mode, do you find that the plugin is still running the tasks that it’s supposed to run, or have those tasks stopped? I’m asking because if the tasks no longer run (to check for updated data in Salesforce, for example), it could be that Action Scheduler is having problems, or that cron on your server is having problems.

Thank you for getting back to me so quickly.

Once the Scheduled Action failed, the logs also stop indeed and there are no more action named “object_sync_for_salesforce_pull_check_records”.

It could very well be that Action Scheduler has issues. I don’t really get any feedback from that.

I flushed my Cache on the server, thinking that might be causing the issue after the server transfer and new setting.

I’m thinking about adding the wp-cron as a run action in the server cron. Perhaps that helps, or at least doesn’t stop if it fails a single time.

Hello, I’m getting back with an update on this. I have since my previous message about three weeks ago cleared the dynamic cache on the server. Although that certainly improved the situation and rather having it stop a couple of times a day they all were running for 3, 4 or even 5 days without failing. It certainly seems like the cache purge helped, but still didn’t quite solve the problem.

I have now disabled the CRON jobs all together by adding

define('DISABLE_WP_CRON', true);

in the wp-config.php file and have set up a real CRON on the server that executes all WordPress CRON/scheduled jobs, per advice from the Web host support. That seems to be working well so far.

I’ll let you know if the problems remain, but this feels quite robust and hoping that this is the solution.

This is helpful. I’m not an expert on cron, but any means, but there is possibly some relevant info on the Action Scheduler website here: https://actionscheduler.org/faq/. They mention that it is fine to run Action Scheduler without WP-Cron, so I’m inclined to think you’ll be fine with this.

Hello again!
Do I understand correctly that the Action Scheduler works independently from CRON-jobs?

Further update on my situation: I have now run the server CRON-jobs and it still seems to stop every now and then, however, the situation looks a bit different.

Whereas, I before received a “Failed” status and I had to go and change the Schedule interval (see more detailed info in my original post), I now don’t see anything going wrong but it stops. And it took a while to figure out because when people told me something went wrong and I looked it immediately worked, I didn’t do any actions.

I soon realized that what I needed to do was to simply log into the WP-backend and everything synced right away. Strange behaviour.

I have been in contact with the Host support and they sent me a log of the CRON jobs and it does run as expected without any errors.

I’m not sure if there is anything I can try here. Let me know if this gives anyone any direction.

My next thing to test is to create a file that doesn’t try to run the schedule but simply performs a manual pull from Salesforce.

I noticed that I possibly can use Object_Sync_Sf_Salesforce_Pull.

I’m thinking about setting up a file doing something like this and run it every two min from the Server CRON:

define( 'WP_USE_THEMES', true ); // I think I need this to get the plugin environment
 require_once( $_SERVER[ 'DOCUMENT_ROOT' ] . '/wp-load.php' ); 
Object_Sync_Sf_Salesforce_Pull();

Or perhaps I can use the web hook or the WP REST API to do it.

How would you recommend going about that?

Thanks in advance!

Best,
Andreas

So Action Scheduler as a library is, according to their own documentation, capable of working independently of WP-Cron. That means you’d have to have some other scheduling system set up to interact with it. I don’t have any experience with doing this, but they do indicate that it has been done.

I would definitely not run Object_Sync_Sf_Salesforce_Pull on a schedule; that is a whole class and running it without a method specified wouldn’t necessarily do anything. What the plugin does with Action Scheduler is run two methods of that class at the intervals you configure: salesforce_pull and salesforce_pull_process_records. I imagine it’s probably possible to do this without Action Scheduler, but certainly it wasn’t built for that.

In any case, to me this sounds like an issue with your host more than an issue with this plugin. Building custom solutions to get around that is beyond the kind of support I can provide.

Hello! Thanks again for getting back to me so quickly!

Sorry I didn’t mean I would call the whole class like that, I was trying to illustrate the idea. ??

That’s helpful! Are there any other actions or commands that triggers a pull in a more conventional way? Is it for instance possible to do it through the WP REST API?

Looks like salesforce_pull is a more general call, but what’s salesforce_pull_process_records? How would that be used, if you don’t mind me asking?

It could very well be the hosting. Though it worked for really long until we renewed our self signed certificates in Salesforce. Then we started having this issue. However, since we moved servers we certainly have a lot more issues with it.

Thanks a lot for your patience and all your help!

Best,
Andreas
