Hello All,

DP 10.40.

We noticed that from time time, like once in an hour but sometimes even more often, DP initiates enormous amount of DNS requests and some of them with incorrect DNS names. As per the logs it requests the following for a single client host:

Record type А – host.domain.subdomain.com 20 types per second (minimum 20. have seen up to 60 times sometimes) - correct hostname

record type А – host.domain.subdomain.com.subdomain.com 20 types per second  - incorrect hostname

record type А – host.domain.subdomain.com.domain.subdomain.com 20 types per second  - incorrect hostname

assuming the high amount of clients in the cell such behavior may create a storm of 12-15000 of requests per second.

any ideas why it may be happening?

thank you!
