Hi Team,

We are facing an issue with Oracle Reports Server where the Reports Engine intermittently crashes with the following error:

REP-56105 : Engine rwEng-0 died with error

oracle.reports.RWException: IDL:oracle/reports/RWException:1.0    
at oracle.reports.utility.Utility.newRWException(Utility.java:1016)    
at oracle.reports.server.EngineManager.manage(EngineManager.java:426)    
at oracle.reports.server.IdleThread.run(IdleThread.java:84)

Environment Details:

  • OS: RHEL 8
  • WebLogic Version: 14.1.2 (Secure Production Mode)

Howdy, Stranger!
