121024  4:04:36 [ERROR] Error running query, slave SQL thread aborted. Fix the problem, and restart the slave SQL thread with "SLAVE START". We stopped at log 'mysql-bin.003717' position 19625392

set foreign_key_checks=0 and restart slave ,then set xxx =1;

if you regard some of erros as meaningless and incline to skip it ,there are two methods:

1.stop slave ;SET GLOBAL SQL_SLAVE_SKIP_COUNTER=1; show slave status; and repeat again and again  until the errors are gone away .
2.vim /etc/my.cnf
skip xxx
