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.
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.

key_buffer_size=104857600
read_buffer_size=52428800
max_used_connections=0
max_threads=512
threads_connected=0
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 52536408 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Çözüm olarak mysql i durdurup *.ibd dosyalarını taşıyıp tekrar cp -a ile kopyaladık ve mysql i çalıştırdık sorunumuz düzeldi.

Basit shell script şöyle :

#!/bin/bash
for i in `ls -a *.ibd`  
do  
  mv $i $i.bak
  cp -a $i.bak $i
done
