     NAME
          strerr - STREAMS error logger daemon

     SYNOPSIS
          Strerr

     DESCRIPTION
          strerr receives error log messages from the STREAMS log
          driver (log(7)) and appends them to a log file.  The error
          log files produced reside in the directory /usr/adm/streams,
          and are named error.mm-dd, where mm is the month and dd is
          the day of the messages contained in each log file.

          The format of an error log message is:
               seq time ticks flags mid sid text

          where:


          seq       error sequence number

          time      time of message in hh:mm:ss

          ticks     time of message in machine ticks since boot

          flags     T : the message was also sent to a tracing process
                    F : indicates a fatal error
                    N : send mail to the system administrator

          mid       module id number of source

          sid       sub-id number of source

          text      formatted text of the error message

          Messages that appear in the error log are intended to report
          exceptional conditions that require the attention of the
          system administrator. Those messages which indicate the
          total failure of a STREAMS driver or module should have the
          F flag set.  Those messages requiring the immediate
          attention of the administrator will have the N flag set,
          which causes the error logger to send the message to the
          system administrator via mail (1).

          Once initiated, strerr will continue to execute until
          terminated by the user.  Commonly, strerr would be executed
          asynchronously.

     CAVEATS
          Only one strerr process at a time is permitted to open the
          STREAMS log driver.

          If a module or driver is generating a large number of error
          messages, running the error logger will cause a degradation
          in STREAMS performance.  If a large burst of messages occurs
          in a short time, the log driver may not be able to deliver
          some of the messages.  This situation is indicated by gaps
          in the sequence numbering of the messages in the log files.
