      Environment (Required on creation): 

      Camunda SpringBoot 7.16.0

      Description (Required on creation; please attach any relevant screenshots, stacktraces, log files, etc. to the ticket):

      Hi ,

      I notice a very strange issue that happens only under high load or when requests are sent in at the same time to Camunda.

      Ex:

      Process instance 1- This gets started and completes fine with a variable ‘status’ = ‘rejected’
      Process instance 2- This gets started and completes fine with a variable ‘status’=‘rejected’ although the variable ‘status’ is never updated/added in this process.

      Conclusion : somehow the value of the variable ‘status’ from Process Instance 1 is seen or updated/available in Process Instance 2.

      It always happens under high load or when concurrent process instances are started of the same process.

      Can someone help me understand why this happens.

      Regards
      Priyotosh

            Hello jila@nuuday.dk,

            Yes you are right, I do see you as authorized contact. In order to analyze your issue, I have raised the issue i.e SUPPORT-12254 in the correct project type being SUPPORT. CAM ticket is not the correct type since it is viewed by everyone and is also not subject to agreed SLA's. For further communication on your issue, we would be doing that as mentioned in SUPPORT-12254. I hope this clarifies stuffs.

            Thanks and Regards,
            Anumeha
