PM64455: INTERMITTENT DISK READ/WRITE ERRORS WHEN USING HTTP/S ADAPTER

APAR status

• Closed as program error.

Error description

• Intermittent Disk Read/Write errors when using HTTP/S Adapter.
  

Local fix

• WTXCQ - WTX00040563
  GK / GK
  Circumvention: None
  

Problem summary

• Users Affected:
  WebSphere Transformation Extender FTP/S, HTTP/S and Event
  Agent/SSL users will be affect, particularly when running in
  multi-threaded environments.
  
  Problem Description:
  Intermittent file I/O errors occurring when running with the
  HTTP/S Adapter.
  
  Platforms Affected:
  ALL
  

Problem conclusion

• The WTX HTTP/SSL component no longer performs a double closure
  on the socket that is connected to the SSL Server.  Before this
  fix, the SSL component would perform a double closure on the
  same socket.  As a result of this fix, multi-threaded
  environments will not run the risk of periodic map and file
  failures, since the SSL component will not perform a file
  descriptor close on the same socket that has started to be used
  by another mapping function.
