Error description
ERROR DESCRIPTION - Migrating process instances that contain unwired subprocesses or linked processes that are not ad hoc might return an inaccurate warning message in the SysOut.log file: ?detected a flowobjects loop of length=xxxx". Additionally, you might notice performance degradation. PRODUCTS AFFECTED IBM Business Process Manager (BPM) Advanced IBM BPM Standard IBM BPM Express LOCAL FIX - None

Problem summary
When instance are being migrated, you might see a similar warning message appear in the SysOut.log file: [11/21/14 11:20:46:392 UTC] 000001d9 wle_migration W com.lombardisoftware.bpd.runtime. engine.cases.MigrateBPDAdhocActivityInstances addAdhocActivitiesFromDiagram Detected a Flowobjects Loop of length=1020. or [2/23/15 12:05:52:478 CST] 00018147 wle_migration W com.lombardisoftware.bpd.runtime. engine.cases.MigrateBPDAdhocActivityInstances addAdhocActivitiesFromDiagram Detected a Flowobjects Loop of length=1. FlowObject Id's in this Loop are=[BPDObjectIdImpl(...)] . Current FlowObject is =..., id=BPDObjectIdImpl(...) . Stopping the precondition cache computation for this loop. This warning is emitted when processes are self-referential or recursive, meaning that a linked process points to the current process definition. However, for unwired subprocesses and linked processes that do not have ad hoc activity support enabled (?The activity runs even though it does not have an inbound flow? is set to false), the activity cannot produce ad hoc activity instances, so updating the precondition cache is unnecessary and detrimental from a performance perspective.
Problem conclusion
A fix is available for IBM BPM V8.5.5.0 that excludes unwired non-ad hoc event subprocesses, subprocesses, and linked processes when updating the precondition cache during instance migration. On Fix Central (http://www.ibm.com/support/fixcentral), search for JR51880: 1.Select IBM Business Process Manager with your edition from the product selector, the installed version to the fix pack level, and your platform, and then click Continue. 2.Select APAR or SPR, enter JR51880, and click Continue. When you download fix packages, ensure that you also download the readme file for each fix. Review each readme file for additional installation instructions and information about the fix.
