2048626 - Severe degradation of PI system performance


You notice a severe degradation of Process Integration (PI) system performance which can manifest itself in many different ways:

  • build up in PI messaging queues on the ABAP side in transaction SMQ2
  • build up in PI messaging queues on the Java side (see SAP Note 1662269 How to Monitor the PI Adapter Framework queues)
  • slow processing of PI messages through transaction SXMB_MONI
  • poor response times for PI related URL's e.g. Runtime Workbench (RWB), PIMON, NetWeaver Administrator (NWA), System Landscape Directoy (SLD) etc
  • slow execution of cache updates
  • high CPU usage



  • PI Release Independent
  • SAP NetWeaver
  • SAP Process Integration
