    used for transfering files. This happens because of a race
    condition in send_file() code path. The stack trace may look
    as follows:
     004ECD10 nbc_locate+0014F0 (DEADBEEFDEADBEEF,
    00000000028D8C68,
       0000000004A90057, 00000000028D8CF8, 0000000000000000,
    0000000002C7E000,
       0000000000000000  ?? )
     00539254 send_file+001414 (??, ??, ??)

    condition.
