Forms core files generated

Dear All,

There are lots of core files generated in $INST_TOP/ora/10.1.2/forms (frmweb core dumps).

Then I changed FORMS_CATCHTERM from 1 to 0.

But issue still exists.

Then I want to relink application based on
Note 356878.1: R11i / R12 : How to relink an E-Business Suite Installation of Release 11i and Release 12.x ? (Doc ID 356878.1)

So, I want to know:
Can relinking have any adverse effect on application's behavior?

Because the issue only happens on production instance, not on cloned test instance.

By the way, can any one tell me why the issue NOT reproducing on newly cloned instance? There are end users do test and try to reproduce the issue, but failed.
