STRERR(1M) Maintenance Commands STRERR(1M)
strerr - STREAMS error logger daemon
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

is the day of the messages contained in each
The format of an error log message is:
error sequence number <time
time of message in hh:mm:ss <ticks
time of message in machine ticks since boot priority level <flags
: the message was also sent to a tracing process F
indicates a fatal error N
: send mail to the system
administrator (hardcoded as root) <mid
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-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
. 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.

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
