APAR status

• Closed as program error.

Error description

• Sporadically during normal build or testing activities using IBM
  Rational ClearCase the dynamic view client with report
  repeatedly "view_server not responding" / "view_server ok"
  messages. This slows down the work as it generates many RPC
  retries.
  
  An example of the errors seen is:
  View server for <SERVER>:<VIEW STORAGE PATH> not responding
  still trying (st=5 er=145)
  View server for <SERVER>:<VIEW STORAGE PATH> ok
  
  WORKAROUND:
  None.

  * PROBLEM DESCRIPTION:                                         *
  * ClearCase users on Oracle Solaris systems sporadically       *
  * experience extremely slow performance of actions in a        *
  * particular dynamic view, accompanied by a series of error    *
  * messages of the form: "View server for <view storage path>   *
  * not responding still trying (st=5 err=145)".                 *

  * RECOMMENDATION:                                              *

Problem conclusion

• Sporadic slow performance of a dynamic view on Oracle Solaris
  occurs when there is a conflict between kernel services using
  the same UDP port for RPCs.  The port assignment is managed by
  the Solaris kernel, but ClearCase has implemented a workaround
  for this problem in versions 8.0.1.21 and 9.0.1.7.
