Hi!
We are using apache ibatis with our MySQL 5.0 database (using innodb
tables), in our web application running on Tomcat 5. Recently we
started getting a number of errors relating to
java.sql.SQLException: Deadlock found when trying to get lock; Try
restarting transaction message from server: "Lock wait timeout
exceeded; try restarting transaction";
We get such errors generally on inserts or updates while applying a
parameter map - see full exception dump below. It takes a tomcat/web
application restart to fix the problem. We've checked "SHOW INNODB
STATUS" on our database and it does not show any deadlock errors (no
LAST DEADLOCK ERROR section).
We would appreciate any suggestions or ideas you have to fix or
alleviate this problem. Thanks :)
Full exception dump:
