i have the following process definition i trie to execude on Camunda 7.24 / CibSeven 2.1 which currently logs during execution many OptimisticLockingException. i could already trace it down that it must have something to do with the multiInstanceLoopCharacteristics when running my subprocess in parallel and using exclusive=false to have real parallel execution of the subprocess and not sequential.
The entire process should solve the problem that too many parallel subprocesses are created and executed (this also has the problem with the OptimisticLockingException). so i want to process a huge collection of elements with max threads that can be configured when starting the process. therefor batches are created and they are processed sequentially while each batch itself is executed in parallel.
What can i do to not get the OptimisticLockingException and still have the result i want to achieve.
i do not want to simply ignore it even though it loooks that everything process wise itself works correct.
