I am using INNODB 5.1.47-community-log MySQL Community Server (GPL). I can see huge lock time in slow queries log as follows
Query_time: 0.000015 Lock_time: 18446744073702.820312 Rows_sent: 0 Rows_examined: 800219
This table has around 21 million rows in it. Can anybody please let me know how to minimize this lock time and what are the reasons of this huge lock time?
