Declare expression stops running on new instance

We have observed several times that some declare expression just don't run when moved to a new instance.

We were asked to delete all the temp directory of tomcat and then restart the instance.

At times it works after restarting.. Is restarting the only way?

How do i check the reason why the expression has not run?

Hi Haria,

In most case all the input data is present, and calculations complete correctly. However problems may occur if some input data is missing. In your case probably issues are when using backward chaining.

In the past we have observed some known issues in older versions. Please have a look at https://community.pega.com/troubleshooting-declarative-expression-does-not-execute-when-decision-rule-provides-no-return-value
