Distributed poller issue

Hi ~~
I have little questions for our situation.
We have about 6000 devices polling by poller(only ping), if only enable fast ping,the status of device seem no update when it off line, if enable fast ping and poller, the message of docker will show “too many connections” sql message.
And my question is that how can i only enable the fast ping and also renew the status of devices.(the poller count is 7)

Modify the SQL parameters and solved it!!
