Hi, we are using the solution from last more than 2 years, but suddenly SoftEther VPN server start using the 100 % CPU, we move the VPN server to another server which have 24 core CPU but the result remain same, there is no change in network an no change in VPN users. We have another server also but that's working fine. no issue.

Ok, well any other option, because we are using this product in our production, so that's why we need a support for this. In case any issue we looses a lot.
