NAME
     strerr - STREAMS error logger daemon

SYNOPSIS
     strerr


DESCRIPTION
     strerr receives error log messages  from  the  STREAMS-based
     log driver (see log(7D)) and appends them to a log file. The
     resultant  error  log  files   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:


           

           error sequence number


          time of message in hh:mm:ss


         time of  message  in  machine  ticks  since  boot
                priority level


         T : the message was also sent to a  tracing  pro-
                cess F : indicates a fatal error N : send mail to
                the system administrator (hardcoded as root)


           module  ID number of source


           sub-ID number of source


          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-based 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 using 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
     There is no restriction to the number  of  strerr  processes
     opening the  STREAMS-based log driver at a time.


     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.
