First thing you can do is to install the debug files by enabling "splitdebug" in /etc/entropy/client.conf Second thing is to run magneto inside gdb and: 1) provide a stack trace for each running thread 2) provide the list of currently running threads 3) use this ~/.gdbinit http://pastebin.sabayon.org/pastie/8873 to be able to introspect CPython interpreter calls 4) recompile dev-lang/python:2.7 with the CFLAGS listed here http://wiki.python.org/moin/DebuggingWithGdb
Besides this, could you test this patch: http://git.sabayon.org/entropy.git/commit/?id=b24e478b21f78d1f8425d4e4d55251381b134591 entropy-updates-service is located into /usr/libexec/ -- Fabio Erculiani
