The better solution would be tailing the log file like /var/log/debug.log Sponsored by: The FreeBSD Foundation Modified: head/tests/sys/kern/sonewconn_overflow.py Modified: head/tests/sys/kern/sonewconn_overflow.py ============================================================================== --- head/tests/sys/kern/sonewconn_overflow.py Tue Oct 6 02:57:37 2020 (r366468) +++ head/tests/sys/kern/sonewconn_overflow.py Tue Oct 6 04:18:42 2020 (r366469) @@ -85,6 +85,8 @@ class UnixTest(GenericTest): class LogChecker(): def __init__(self): + # Clear the dmesg buffer to prevent rotating causes issues + os.system('/sbin/dmesg -c > /dev/null') # Figure out how big the dmesg buffer is. self.dmesgOff = len(check_output("/sbin/dmesg"))
