      I consider disabling the ExternaliseCanonicalModelLambda is not an option because if it can be enabled on customers environments, we can face performance issues there.

    Description

      java.lang.OutOfMemoryError: GC overhead limit exceeded during execution of org.drools.benchmarks.turtle.buildtime.BuildKieBaseFromContainerBenchmark.* when creating the kiebase. You can see the stack trace on [1].

      After disabling ExternaliseCanonicalModelLambda*, the benchmark was able to run normally. The memory consumption is around than 2Gb[2], otherwise it goes to the infinite (I tried until 12Gb).

      *I changed the drools code base but it can be disabled programmatically

      [2] 2,2Gb (attachment [memory_consumption.jpg]), sometimes 3,3Gb (attachment [memory_consumption2.jpg])

          Bug - A problem that impairs or prevents the functions of the product. RHPAM-2738 OOME on org.drools.benchmarks.turtle.buildtime.BuildKieBaseFromContainerBenchmark

          • Blocker - To be worked above all other priorities. This term is chosen when the severity of the issue is very high, has no workaround, or the effort for the change is comparatively low. Issues that may be very publicly visible and could generate significant media attention may also drive a higher priority.

          Enhancement - An enhancement to or refactoring of existing functionality that is not configurable by an end user (typically a change made by an internal team that affects users) DROOLS-5105 Disable Lambda externalisation default and add configuration to public api

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
