  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>

            <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(1).  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 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 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.
