  ****************************************************************
  SESSION formatting option for PFSMIN  component trace generates
  incorrect output and fails with an abend0C4.
  
  The SESSION formatting option for the SYSTCPIP component trace
  containing PFSMIN trace entries for readv or writev socket
  calls do not format correctly.  The formatted output for these
  entries will contain "Record Corrupted - Unknown PFS Entry"
  and will exceed the report line length.  The report line overrun
  results in an abend0C4 when scrolling to the end of the report
  or when the report is exited.
  
  Example report (lines truncated):
  IP CTRACE COMP(SYSTCPIP) SUB((TCPIP)) OPTIONS((SESSION))
