问题
I am using sonarqube 4.5.4 with mysql database.
I got this exception when running analysis on my projects :
INFO o.d.m.sonar.runner.RunSonarVisitor - ### Error updating database. Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLTransactionRollbackException: Deadlock found when trying to get lock; try restarting transaction

Could you help me please.
回答1:
Can you try innodb_locks_unsafe_for_binlog = 1 in your config?
Here is documentation: effectively that means select for update makes table lock. More information about locks in innodb.
Still there are some question marks here, but that is my first idea. If that is still a problem... let's start from that binlog settings.
