java.lang.IllegalStateException: Imbalanced frame stack! (exit() called too many times) !

If you started using SpringSource Insight,It's highly recommended to increase the memory of the tc Runtime Instance to more than what your application requires on its own . The following is the exception you might see in case there is not enough memory.
type Exception report
message

descriptionThe server encountered an internal error () that prevented it from fulfilling this request.
exception
java.lang.IllegalStateException: Imbalanced frame stack! (exit() called too many times)
com.springsource.insight.intercept.trace.ThreadLocalFrameBuilder.exit(ThreadLocalFrameBuilder.java:61)
com.springsource.insight.collection.DefaultOperationCollector.exit(DefaultOperationCollector.java:111)

note The full stack trace of the root cause is available in the VMware vFabric tc Runtime 2.6.2.RELEASE/7.0.22.A.RELEASE logs.

There are few options to resolve this issue.
  1. Increase the max heap
    For example: -Xmx512m
  2. or max PermGen size JVM option.
    For example: -XX:MaxPermSize=256m
  3. Increase the Spring insight max frame
    For example: -Dinsight-max-frames=6000
OR you can have all of the above JVM parameters.
