# Description: reconnects to log socket if a write fails with
|
||
|
|
# ECONNREFUSED or ENOTCONN -- similar to reopen
|
||
|
|
# in syslog routines provided by glibc.
|
||
|
|
# Happens if the log socket (provided by syslog
|
||
|
|
# daemon) has been reopened. Can be triggered by
|
||
|
|
# "rcsyslog reload" while syslog-ng is used.
|
||
|
|
# See also Bugzilla Bug #27971.
