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 http://kb.askmonty.org/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: 10.1.8-MariaDB-debug-log key_buffer_size=1048576 read_buffer_size=131072 max_used_connections=1 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 = 62963 K bytes of memory Hope that's ok; if not, decrease some variables in the equation.   Thread pointer: 0x0x0 Attempting backtrace.
