NAME
       strerr - STREAMS error logger server

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.

FILES
       /usr/adm/streams/error.mm-dd

SEE ALSO
       strace(1M), log(7).

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 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.
