# This is test case from practice, with the version we introduced it, it
# caused a deadlock during processing.
# We added this as a standard test in the hopes that iw will help
# detect such things in the future.
#
# This is a test that is constructed similar to asynwr_deadlock2.sh, but
# can produce problems in a simpler way.
#
# added 2010-03-18 by Rgerhards
# This file is part of the rsyslog project, released under ASL 2.0
