  If a 6.0.2 server exhibiting the symptoms in this APAR send
  IIOP requests to another WebSphere server running 6.1, the 6.1
  controller region could terminate with the following message:
  BBOO0035W TERMINATING THE CURRENT PROCESS, REASON=C9C21A4D,
  followed seconds later with SDC3 REASON=000C0006.

Problem summary

  ****************************************************************
  The WebSphere Application Server for z/OS controller address
  space suffers the following errors while attempting to send a
  GIOP message over TCP/IP to another server:
  
  BBOO0160E Function send() failed with RV=3140, RC=0,
  RSN=00000000, [EDC5000I No error occurred. (errno2=0x05230138)]
  
  BBOO0044E Internal communications error: REASON=C9C20C5E
  
  The send() fails with a non-zero return value (RV) that
  matches the message length of a GIOP message sent by another
  thread that is also sending GIOP messages to the same target
  server as the failing thread.  The failure occurs because a
  timing window exists where one thread could send() its own
  GIOP message but receive the return value from the send() of
  the other thread's GIOP message.  The other thread's return
  value is not expected by the first thread; therefore the first
  thread fails its request.
  

Problem conclusion

• The timing window was closed such that two threads can no
  longer interfere with each other's send() return values.
  
  APAR PK84457 is currently targeted for inclusion in
  Service Level (Fix Pack) 6.0.2.37 of WebSphere
  Application Server V6.0 for z/OS.
