  The SAP error message UJA_EXCEPTION383 indicates that the shared object memory allocated for the SAP environment is insufficient. This can occur in various scenarios, particularly when the system is under heavy load or when there are many concurrent users or processes.
  Cause:
  The error is typically caused by one or more of the following factors:
  
  Insufficient Shared Memory Allocation: The shared memory settings in the SAP system are not configured to handle the current workload.
  High Load: The system is experiencing a high number of concurrent users or processes, which requires more shared memory than is currently allocated.
  Configuration Changes: Recent changes in the system configuration or an increase in the number of users or processes can lead to this issue.
  Memory Leaks: There may be memory leaks in the application or in custom code that is consuming more memory than expected.
  
  Solution:
  To resolve the UJA_EXCEPTION383 error, you can take the following steps:
  
  
  Increase Shared Memory Allocation:
  
  You need to increase the shared memory settings in the SAP system. This can typically be done by adjusting the parameters in the instance profile.
