IT08191: Application error gets logged in Windows event log for Common Agent managed systems with Source: PerfNet and Event ID: 2006

APAR status

• Closed as documentation error.

Error description

• For Common Agent (CAS) managed systems running on Windows
  operating system with more than 32 processors, user may
  periodically see an application error with ID 2006 and source as
   PerfNet getting logged in Windows application event log.
  
   Source: PerfNet
   Event ID: 2006
   Unable to read Server Queue performance data from the Server
  service.
   The first four bytes (DWORD) of the Data section contains the
  status
   code, the second four bytes contains the IOSB.Status and the
  next four
   bytes contains the IOSB.Information.
  
  Impact:
  User will get confused with the Application Error for CAS
  service getting logged into Windows Event log.  Also, CAS
  service may or may not work correctly.
  

Local fix

• This is a permanent limitation for Common Agent managed systems.
    To resolve this issue, user needs to restrict the number of
  processor cores to no more than 32 for the target system.
  

Problem summary

• On Windows systems, there is a limitation on the Microsoft
  performance provider PerfNet.dll. It can only support a maximum
  of 32 processors.
  
  With IBM Systems Director (ISD) Common Agent (CAS) being a 32
  bit application, each time CAS service is starting, the resource
  monitor will be initialized and use this provider to get the
  number of processors. If more than 32 processors are available
  for the system, a Windows application error (ID:2006) will be
  logged into the Windows event log.
  
  The mentioned scenario will be included in the IBM Systems
  Director online documentation.
