我使用mysqlslap在mysql服务器上运行基准测试。但有时池中的最后一个线程没有执行和关闭连接。它保持睡眠状态。
mysql> show full processlist;
+-----+------+-----------------------+-----------+---------+------+-------+-----------------------+
| Id | User | Host | db | Command | Time | State | Info |
+-----+------+-----------------------+-----------+---------+------+-------+-----------------------+
| 2 | root | 122.178.231.xxx:15832 | mysqlslap | Sleep | 740 | | NULL |
| 106 | root | localhost | NULL | Query | 0 | NULL | show full processlist |
+-----+------+-----------------------+-----------+---------+------+-------+-----------------------+
2 rows in set (0.00 sec)
有什么想法吗？它经常发生:(
这是我执行的命令。
mysqlslap -h IP_address -u root --auto-generate-sql --concurrency = 100 -pPASSWORD -vvv --number-of-queries = 2500
