    OPMNCTL connection to opmn does not work intermittently

    632023
      Using Oracle HTTP Server from DB10.2 companion CD, patched to 10.2.0.4
      on Oracle Enterprise Linux 5.2

      When trying to start opmnctl status I get often (not always) following message:
      Unable to connect to opmn.
      Opmn may not be up.

      But ps -ef | grep opmn shows that opmn is up
      oracle 1907 32391 0 09:23 pts/2 00:00:00 grep opmn
      oracle 19989 1 0 09:07 ? 00:00:00 /oracle/product/10.2.0_apache/opmn/bin/opmn -d
      oracle 19991 19989 4 09:07 ? 00:00:42 /oracle/product/10.2.0_apache/opmn/bin/opmn -d

      If re-executing the command serveral times it will work after trying about 3 to 10 times

      opmnctl ping sometimes works, sometimes failes too

      same issue with opmnctl startproc ias-componet=HTTP_Server
      Somtimes it failes with:
      opmnctl: starting opmn managed processes...
      ================================================================================
      opmn id=ds83-235-87-118:6200
      0 of 1 processes started.

      ias-instance id=standalone
      ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
      ias-component/process-type/process-set:
      HTTP_Server/HTTP_Server/HTTP_Server

      Error
      --> Process (pid=760)
      failed to start a managed process after the maximum retry limit
      Log:
      /oracle/product/10.2.0_apache/opmn/logs/HTTP_Server~1

      somtimes startproc works and after trying several times status will work too and show that HTTP-Server is up...
      opmnctl status
      Processes in Instance: standalone
      ------------------------------------------------+---------
      ias-component | process-type | pid | status
      ------------------------------------------------+---------
      HTTP_Server | HTTP_Server | 24516 | Alive
      LogLoader | logloaderd | N/A | Down
      dcm-daemon | dcm-daemon | N/A | Down


      Can anybody give me some hints how to identify the problem?
      Thank you very much for your help.
