com.atlassian.crowd.exception.OperationFailedException: Requested array size exceeds VM limitCause
Application attempted to allocate an array that is larger than the heap size. In most cases the problem is either a configuration issue (heap size too small), or a bug that results in an application attempting to create a huge array, for example, when the number of elements in the array are computed using an algorithm that computes an incorrect size.
Resolution
Increase the heap size memory as per this document.
