SAP PO | Failed to get lock

604 Views

All,

Since a few days, we get this error on our productive SAP PO 7.4 system:

Transmitting the message to endpoint <local> using connection IDoc_AAE_http://sap.com/xi/XI/System failed, due to: com.sap.engine.messaging.runtime.ClusterException: Failed to get lock for EOIO_MD_XI_OUTBOUND_<message_type>__<receiver>. Reason: com.sap.engine.frame.core.locking.TechnicalLockException: Cannot lock [I2016072214452383200000<machine_name>..................252093350, $service.msg_BC_MSG, EOIO_MD_XI_OUTBOUND_<message_type>__<receiver, X]; unknown return-code (returncode = -1).

Context

  • IDOCs being sent from our SAP ERP system to the SAP PO system.
  • QoS is EOiO.
  • Multiple receiving systems
  • graphical mapping

Any ideas or leads?

Thanks a lot.

Dimitri
