Hi, In one of my tool unix command "dd" to convert and copy a file has been used. Most of time this commands runs well while executing with following options dd ibs=20b if=/tmp/test3 output: 16019+1 records in 320380+1 records out 164034561 bytes (164 MB) copied, 4.92556 s, 33.3 MB/s With coreutil version 8.4 I am facing following error:     dd: writing in "Standard stdin": The connection was reset by the communication partner output: 102+0 records in 2036+0 records out 1042432 bytes (1,0 MB) copy, 0,00816693 s, 128 MB/s what could be the reason for this error? dd --version dd (coreutils) 8.4 Copyright (C) 2010 Free Software Foundation, Inc.
