Hi,
We are testing on kernel 3.18, ovs current master, gre tunnels / xen
server. Following python script leads to fast ovs-vswitchd memory grow
(1GB / minute) and finally OOM kill:
import random, socket, struct, time
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
while True:
ip_raw = struct.pack('>I', random.randint(1, 0xffffffff))
ip = socket.inet_ntoa(ip_raw)
try:
sock.sendto("123", (ip, 12345))
except:
pass
#time.sleep(0.001)
During this test ovs did not show growing flow number, but memory still
grows.
If packets are sent too slow, then memory never grows - uncomment
time.sleep line above.
Best,
Adam
