[Samba] Any risks of modifying tcp_keepidle etc params?

[Chenyehua]

Hi folks
   Recently, I find that the number of the smbd connections may increase if the network is abnormal. And the repeated connections will exist for a long time (which is not accepted for me)
   So, I modify the following params and shorten the existing time of those repeated connections:
       TCP_KEEPCNT      3
TCP_KEEPIDLE       60
TCP_KEEPINTVL    15
My concern is that:
Are there any risks of modifying above params to those values?
