encounter SqlTransactionRollbackException when complete a user task
i have encountered an exception 'SqlTransactionRollbackException' when i invoked the API 'taskService.complete(Strin taskId,map variables)' to complete a User Task frequently; The probability of encountering this exception is high to 40%.The User Task's property 'asynchronous' is set by 'false',and 'exclusive' is 'true'. what problem cause this exception? deadlock? WHY ?
If you could provide a bit more detail or even better a code example that might help. How are you invoking the rest call? Are choosing from a list at random, one at a time or in parallel and at what rate?
