    Description

      We have BPMS 6 running and are attempting to claim/start/complete tasks concurrently with 400 users. The average time for each task operation is a little over 30 seconds, and we are seeing a majority of our threads blocking on a TaskTransactionInterceptor. I have attached a thread dump that shows this.

      All the blocked threads are blocking on the synchronized <T> T execute(Command<T> ) method.

      Our deployment is using the Per_Process_Instance runtime strategy.

          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) JBPM-4229 Revisit usage of shared instance of TaskService

          • 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.
