【问题描述】：
我在 Windows Server 2008 R2 上使用 MySQL 5.7.14 x64
有时（一天中的随机时间）mysql 因此堆栈跟踪而崩溃
11:44:40 UTC - mysqld got exception 0x80000003 ;
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.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.
key_buffer_size=8388608
read_buffer_size=65536
max_used_connections=369
max_threads=2800
thread_count=263
connection_count=263
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 3195125 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
Thread pointer: 0x2ee2b72b0
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...

不明白为什么事务1111758443 Waiting for table level lock？
为什么事务 1111759716 会锁定 102060778 行，而它只从外部文件加载一个并且它显示在撤消日志条目 1 中？
由于已知的原因，我必须对这种巨大的锁和崩溃进行哪些调查。
谢谢！
【问题讨论】：
-
a) 你有 myisam 表吗？ b）检查哪些其他表被可能与第一个交互的第二个事务锁定/使用 c）检查您的表上是否有触发器、外键/级联删除可能与其他表中的一个交互 d）我会尝试先导入到不同的表（没有事务）。加载后，将其转移到目的地，可能是小批量。尽管我不知道您导入脚本的其余部分以及您导入了多少行，但我怀疑这是您问题的根源。 e) 也许更新 mysql。
