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  atten-
     tion  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  mes-
     sage 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.
