NAME
       strerr -	STREAMS	error logger daemon

SYNOPSIS
       strerr

DESCRIPTION
       strerr  receives	 error	log  messages from the STREAMS 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 : indicates
	     a fatal error N : send mail to the	 system	 administrator	(hard-
	     coded 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
       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	admin-
       istrator	 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.

       STREAMS Programming Guide

NOTES
       There is	no restriction to the number of	strerr processes  opening  the
       STREAMS 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.
