if the block always happen at the same exactly location, maybe this is an problem related to map files (client files != server files)

but if this is happening at random locations, maybe it's something related to walk packets. If your server is running on windows, try disabling EF_FastWalkPrevention (this setting only works fine on linux, which have high precision calculations to make sphere fastwalk check works properly). You can also tweak the WalkBuffer / WalkRegen values to check if you get better results
