    I have an FPS game and the clients and the server sends a lot of messages but at any time at random the game can crash on the second message to the thousand message with this error:

    ========== OUTPUTTING STACK TRACE ==================

    0x00007FFC2A4C1EE7 (UnityPlayer) memcpy
    0x00007FFC29A18319 (UnityPlayer) UNET::VirtualUserHost::SendInt
    0x00007FFC29A17644 (UnityPlayer) UNET::NetLibraryManager::Send
    0x00007FFC29A23742 (UnityPlayer) NetworkTransport_CUSTOM_SendWrapper
    0x000002635949B5E1 (Mono JIT Code) (wrapper managed-to-native) UnityEngine.Networking.NetworkTransport:SendWrapper (int,int,int,byte[],int,byte&)
    0x000002635949B4D3 (Mono JIT Code) UnityEngine.Networking.NetworkTransport:Send (int,int,int,byte[],int,byte&)

    How can I fix it? Sometimes the game works just fine and sometimes it crashes randomly..

    It is possible only if you provide wrong length of your buffer for example byte[] b = new byte[10]; send( ...,b, 20); // crash... check this please
