server forgets assigned ips

[vix]

I have many servers all are using softether with the same script

I assign each customer a unique dedicated ip address and it has been working fine for several months

but one server all of a sudden is starting to have issues where every couple days like 4-7 days it forgets all assigned ips to users and customers can't connect to their vpns because of it

so I have to run vpn script again and that fixes the issue of assigning the correct ips to the users, but i have no idea what could be causing it to forget the assigned ips as this has never happened before, any ideas?

Note - Ironically enough this server does have the most ips out of all my other servers, about 350 ips on this one while the others have 200-250 ips, could this be causing an issue? Any ideas on how to fix it

using CentOS 6.X on all servers only one server is having this problem

SoftEther Virtual DHCP is very simple DHCP server.
So, please use external DHCP server.
