Syncookie threshold 1994 exceeded
Hi team,
We have BIG IP LTM device in cluster for our production system, we are receiving below error message during peak window and suspect some of genuine connections are getting dropped due to SYN Protection. Few customers also complained that few financial transaction getting dropped intermediately.
Syncookie threshold 1994 exceeded, virtual = 172.16.170.55:443
Limiting open port RST response from 501 to 500 packets/sec
kindly suggest your inputs/solution to mitigate this issue.
