   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 /var/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>

              <seq>     error sequence number

              <time>    time of message in hh:mm:ss

              <ticks>   time of message in machine ticks since boot priority
                        level

              <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.  The priority level usually has no
         meaning in the error log but will have meaning if the message is also
         sent to a tracer process.

         Once initiated, strerr continues to execute until terminated by the
         user.  It is commonly executed asynchronously.

   NOTES
         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 are generated 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.
