This as seemingly solved the glitch with amadmin: ~# ~amanda/sbin/amadmin top tape The next Amanda should go onto 3 new tapes. The next 3 new tapes already labelled are: NEO-T48-B00028, NEO-T48-B00029, NEO-T48-B00030 Thanks Jean-Louis, jf > > Thanks, > jf > > > > > Jean-Louis > > > > On 10/02/17 09:35 AM, Jean-Francois Malouin wrote: > > > * Jean-Louis Martineau <jmartin...@carbonite.com> [20170210 07:54]: > > >> Jean-Francois, > > >> > > >> I was not able to find the problem with the stacktrace. > > >> > > >> Do you have valgrind installed on your system?, if yes, can you run the > > >> following command: > > >> G_DEBUG=gc-friendly G_SLICE=always-malloc valgrind --trace-children=yes > > >> --log-file=valgrind.amtape.output --leak-check=full > > >> --leak-resolution=high --track-origins=yes amadmin top tape > > >> > > >> And send me the resulting valgrind.amtape.output file. > > > The output from valgrind file is attached. > > > > > > cheers, > > > jf > > > > > >> Jean-Louis > > >> > > >> On 09/02/17 02:19 PM, Jean-Francois Malouin wrote: > > >>> * Jean-Louis Martineau <jmartin...@carbonite.com> [20170209 14:09]: > > >>>> Jean-Francois, > > >>>> > > >>>> Can you run amadmin in gdb and get a stacktrace? > > >>>> > > >>>> $ gdb ~amanda/sbin/amadmin > > >>>> (gdb) run top tape > > >>>> (gdb) bt > > >>>> (gdb) quit > > >>>> > > >>>> Jean-Louis > > >>> Here you go: > > >>> > > >>> amanda@dow:~$ gdb ~amanda/sbin/amadmin > > >>> GNU gdb (Debian 7.7.1+dfsg-5) 7.7.1 > > >>> Copyright (C) 2014 Free Software Foundation, Inc. > > >>> License GPLv3+: GNU GPL version 3 or later > > >>> <http://gnu.org/licenses/gpl.html> > > >>> This is free software: you are free to change and redistribute it. > > >>> There is NO WARRANTY, to the extent permitted by law.
