  ****************************************************************
  When users attempt to initiate the IHS web server on the Windows
  operating system, it encounters a failure to start following the
  activation of ODRLIB.
  This problem stems from a byte buffer overflow leading to an
  unforeseen termination of the process. Notably, this issue seems
  exclusive to the Windows platform, as an extra slash in the
  format
  string is not adequately handled, triggering the malfunction.
  

Problem conclusion

• To safeguard against the premature termination of the IHS web
  server, we have rectified the oversight concerning additional
  characters in the format string, thereby effectively mitigating
  the byte overflow issue.
  
  No further adjustments are necessary; simply install the
  provided fix pack to implement the resolution.
  
  The fix for this APAR is targeted for inclusion in fix pack
  8.5.5.26, 9.0.5.20.
