My last error.log Logfile is from the 08. July and the system won't create newer Logfiles.

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.

To report this bug, see https://mariadb.com/kb/en/reporting-bugs

We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed, 
something is definitely wrong and this may fail.

Server version: 10.0.30-MariaDB-0+deb8u2
key_buffer_size=16777216
read_buffer_size=131072
max_used_connections=0
max_threads=153
thread_count=0
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 351246 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Thread pointer: 0x0
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...
stack_bottom = 0x0 thread_stack 0x30000
The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains
information that should help you find out what is causing the crash.

Right now i tried to move the content from /var/lib/mysql to a fresly installed server with only MariaDB installed.

(Stop MariaDB Server -> backup /var/lib/mysql directory on new server > tar /var/lib/mysql directory from not working server > copy tar-file to new server > extract > start MariaDB Server => Failed)

I have no clue what to do next - all i need is to backup a single database.

System:

  • Raspbian (latest)
  • MariaDB Ver 15.1 Distrib 10.0.30-MariaDB for debian-linux-gnueabihf

Looking forward for some help

Thanks in advance
