  ****************************************************************
  01.For output character set referring to state-dependent
     encoding (i.e f it contains the multibyte characters with
     shift-states like IBM-930), iconv conversion may leave the
     descriptor and output buffer in an expected shift state. In
     such case, the next conversion would be started from the
     state set from previous conversion. The current conversion
     may be messed up.
  02.During the processing of audit file rotation in logging, all
     old audit logs are processed using a file stream by RSE
     daemon. The files descriptor for these streams if not closed
     would be accumulated over the life span of the RSE daemon
     until it is recycled.
  03.During the directory listing of a partition dataset, when an
     abend occurs due to a closing of an invalid dataset DCB
     handle, a recursive chain of the abend may occur.
  

Problem conclusion

• 01.After an iconv() conversion, as recommended, reset to the
     initial state for the iconv descriptor and the output buffer
     by calling an iconv() call with a NULL input (or point to a
     NULL).
  02.RSE daemon when processing audit log rotation, it misses to
     close the file stream opened to access the old audit logs.
     The fix is to close the file stream properly when the
     processing is done.
  03.The condition handler of the partition dataset directory
     listing routine attempts to close the dataset DCB handle
     when it was flagged as opened. In some error listing
     condition, when the DCB handle was not set properly, calling
     close function on it may cause the abend, leading to a
     repeated condition handler routine invocation. Resetting the
     dataset open flag when closing the DCB preventing the
     recursive behavior when the DCB is invalid. This fix does
     not resolve the original issue of the cause for an invalid
     DCB handle.
