Error description

• IEA794I SVC DUMP HAS CAPTURED: DUMPID=019 REQUESTED BY JOB
  (xxxxxxxx) DUMP TITLE=OMEGAMON XE DB2 PERFORMANCE EXPERT HIGH
  CPU
  
  panel ZEDSN
  (R  RESOURCE MANAGERS --> C  EDM POOL --> A-EDM POOL SNAPSHOT))
  
  When the Classic Interface requests EDM POOL SNAPSHOT SUMMARY
  data from PE Server and the size of the provided data buffer
  is not large enough to store the available data, PE Server
  returns the request indicating data truncation. The display
  logic re-allocates a larger buffer and repeats the request
  without clearing the attributes indicating data truncation.
  Depending on the data volume available on PE Server side this
  may result in a loop causing high CPU in the DB2 interface
  task FPEVDB2I.
