Quartz scheduler is frozen

[danies8]

Hi
I'm using quartz scheduler in net 8.
I schedule jobs in worker service and they work
As expected.
But from time to time it could be days
The scheduler stop working.
No error seen .
Can you provide help?
Thanks in advance,

Any idea ? is very important?

Well I'm not really a clairvoyant, you need to enable logging and trace what is happening. You need to understand that this is the same thing as I would ask you about why my car won't start.

I would like to ask you.
I'm using worker service .NET 8 and log 4 net for logging.
How do i enable logging and trace for what is happening ?

[lahma]

Please see the examples in this repository. They have logging.

What i need to do in this exception, i have many jobs running?
Does scיeduler stop working in this case(frozen)?

[danies8]

@lahma
Our production app is frozen from time to time , do you or something else give support to quartznet?
We need it!!

Based on configured schedule, the given trigger '28.2' will never fire.
What is the schedule for this job? That error appears to log when Quartz attempts to resolve ComputeFirstFireTimeUtc and is unable to get a valid FirstFireTime,

@lahma @jafin @omrikaufman
I run my app one month without problems with alot of files .After one month the scheduler is frozen.
I'm using QUARTZ Version 3.8.0
How can i know when the sceduler is frozen in order to send email to our customers to restart the scheduers.
Do you have new version that solved the problem maybee?
Your quick answer will be appreciated.
