IT28900: ADD CODE TO PUT A MAX LIMIT ON HOW MANY WSAEWOULDBLOCK ERROR

APAR status

• Closed as program error.

Error description

• Add code to put a max limit on how many WSAEWOULDBLOCK
  errors are allowed before exiting the POP3 comm session
  

Local fix

•      Add code to put a max limit on how many WSAEWOULDBLOCK
  errors are allowed before exiting the POP3 comm session
  

Problem summary

• PROBLEM DESCRIPTION:  A comm receive session intermittently
  hangs when opening a POP3 session due to the recv socket API
  call returning a
  WSAEWOULDBLOCK error every time its retried in this session.
  Need to add a max limit on the number of retries allowed before
  aborting the
  POP3 session.
  
  USERS AFFECTED: Any user doing a POP3 comm receive session.
  

Problem conclusion

• FIX DESCRIPTION:  Added code to limit how many times recv can
  return a WSAEWOULDBLOCK error before having ReadString function
  return a
  WSAETIMEDOUT error which errors the comm session.  This retry
  limit value is read in at the start of each comm receive session
  from this
  new registry setting:
  
  Key: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Sterling
  Commerce\Commerce:Connection
  Value Name: RecvSocketRetryLimit
  Value: any number greater than 0 (0 = no retry limit)
  
  If this registry setting is not found, it will create this
  registry value and set it to 0 (off).  Users can change this
  value in between comm
  sessions.
  

Temporary fix
