Error description

  • A long-running simulation that has many instances and tokens

    java.lang.OutOfMemory error.

Local fix

Problem summary

  • IBM Process Designer fails with a java.lang.OutOfMemory error
    when you run a simulation that has many tokens waiting on a join
    gateway. A heap dump analysis shows
    com/lombardisoftware/simulation/bpd/impl/worker/JoinImpl$1 as a
    memory-leak suspect. A new listener object was being created for
    each waiting token, which quickly exhausts the available heap
    space in certain scenarios.
    

Problem conclusion

  • A fix is available for IBM BPM V8.0.1.2 that avoids creating a
    new listener object for each waiting token, thereby preventing
    the exhaustion of heap space and subsequent
    java.lang.OutOfMemory error.
