PK77286: CONNECTION NOT RESET AFTER SOAP RESPONSE 500

SCA Feature Pack Fix Pack V1.0.0.1 for WebSphere Application Server V7.0 release
1.0.0.3: WebSphere Application Server V7 Feature Pack for SCA Fix Pack 1.0.0.3

APAR status

• Closed as program error.

Error description

• This problem affects all operating systems. When using web
  services with the Feature Pack for SCA, a connection that gets
  a 500 response code will not be reset correctly, resulting in
  eventual depletion of all available HTTP connections. At this
  point the server must be restarted before it can function again.

Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of WebSphere Application Server   *
  *                  Feature Pack for Services Component         *
  *                  Architecture (SCA) that deploy applications *
  *                  with service references over the Web        *
  *                  Service Binding.                            *
  ****************************************************************
  * PROBLEM DESCRIPTION: Web Service Binding requests            *
  *                      receiving HTTP 500 response codes do    *
  *                      not properly return their HTTP          *
  *                      connections to the connection pool      *
  *                      resulting in transport timeouts         *
  *                      waiting for an HTTP connection.         *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When service requests over the Web Service Binding receive an
  HTTP 500 response code the HTTP connections are not properly
  detached making them unable to be returned to the connection
  pool. This results in depletion of the HTTP connection pool
  resulting in transport timeouts waiting for an available HTTP
  connection.  This condition can only be resolved by recycling
  the server process.
  

Problem conclusion

• Add code in exception handling to detach the input stream
  allowing the HTTP connection to be returned to the connection
  pool and reused.
  
  The fix for this APAR is currently targeted for inclusion in
  fixpack 1.0.0.1 of SCA Feature Pack on WebSphere
  Application Server V7.0. Please refer to the Recommended
