SQLSTATE[40001]: Serialization failure: 1213 Deadlock found when trying to get lock.

[t-heuser]

Describe the bug I'm getting a random Serialization failure which gets thrown by this extension. It happened at night without anyone being on the system. All information about the error can be found in the sentry error here: https://api.npoint.io/8b091f6126a77dad815f

To Reproduce Steps to reproduce the behavior: Let cronjobs run.

Expected behavior No Deadlock occurs.

Environment (please complete the following information):

• OS: Linux 4.18.0-240.1.1.el8_3.x86_64
• Browser: not applicable
• Cron Job Manager Version: 1.11.3
• Magento Version: 2.4.1
• PHP Version: 7.4.14

Edit: Just saw that the error was thrown before 17 times because of this module. But the times before we had a stack trace. It get's thrown in the ScheduleRepository when trying to save the schedule resource. If you want I can also post the json of the sentry error but unfortunately I cannot give you access to our sentry.

@peterjaap I'm not working at the company anymore which I created the issue for. I'll ask someone from the company to provide further details.
