# Cron job error

### Bug/Issue&#x20;

There are people still have issue with **order driver match/taxi booking match**. If you check your error log in your backend and see any error log similar to the ones below:

```
Call to undefined function Illuminate\Queue\pcntl_async_signals() {"exception":"[object] (Error(code: 0): Call to undefined function Illuminate\Queue\pcntl_async_signals() 
```

```
Call to undefined function Illuminate\Queue\pcntl_run_signals() {"exception":"[object] (Error(code: 0): Call to undefined function Illuminate\Queue\pcntl_run_signals() 
```

This mean your php was unable to run the **queue jobs** because your php server has disable some functions required to run the queue jobs.&#x20;

### Solution:

1\. You have to either contact your hosting provider and ask them to enable all functions related to queue jobs.&#x20;

2\. You enable them yourselves if you have access to the php.ini file on your server: [https://www.simplified.guide/php/disable-functions](https://www.simplified.guide/php/disable-functions)
