Hello

I am using **Jenkins** version **2.235.5**.

The application is installed on **Windows 10** machine.

I got the **parameterized scheduler** plugin ( **version 1.0** ) to manage Cron execution for Jenkins pipelines.  
I am careful to make the concurrent process running at different times in the cron definition.

For some reason, sometimes, the scheduler stops to work and I need to restart Jenkins to get it running again.

Nothing appears on the log file and it never happen for free style projects but **only for pipelines**.

I was wondering if someone is facing such kind of issue?

Thanks

I’ve not seen any report from others of any case where the scheduler stops working. [Jenkins 2.235.5](https://www.jenkins.io/changelog-stable/2.235.5/) was released 4 years ago. It has many known security vulnerabilities. Upgrading to a newer version may resolve your issue. If it does not resolve your issue, it will still increase the chances that others are willing to help.
