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:

       <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 : indi‐
		  cates a fatal error N : send mail to the system  administra‐
		  tor (hardcoded as root)

       <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 excep‐
       tional conditions that require the attention of the system  administra‐
       tor.    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 sys‐
       tem  administrator using mail.  The priority level usually has no mean‐
       ing 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.

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

	   error log file.

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  perfor‐
       mance.  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 situa‐
       tion  is indicated by gaps in the sequence numbering of the messages in
       the log files.
