• What is the cause and solution for SAP error message WZ380 - Sending failed for work item &1: Pipe could not be opened ?

  SAP Error Message:
  WZ380 Sending failed for work item &1: Pipe could not be opened
  
  Cause
  This error occurs when SAP tries to send a work item (usually in the context of workflow or background processing) through an inter-process communication (IPC) mechanism, specifically a pipe, but fails because the pipe cannot be opened. Pipes are used internally by SAP to communicate between different processes or work processes.
  Common causes include:
  
  Operating system level issues: The pipe resource is not available or cannot be created/opened due to OS restrictions or resource exhaustion.
  Permission problems: The SAP user or process does not have the necessary permissions to create or open the pipe.
  System resource limits: The maximum number of pipes or file descriptors has been reached.
  Incorrect or corrupted SAP kernel or OS configuration: The kernel or OS environment might be misconfigured or corrupted.
  Work process or dispatcher issues: The work process that should receive the pipe communication is not running
