panic: test timed out after 5m0s

[inevity]

When running the last test changlog, met this error as title show.
My test env is a kvm vm .

Have set mysqld,
innodb_lock_wait_timeout=500
transaction-isolation = READ-COMMITTED

But cannot fix this issue.
Then i change the test timeout to 3000s /50m to check whether the test pass.

first met some datarace warning,
then

2019-07-24T15:44:34.629+0800 ERROR changelog/mysql.go:841 Error 1205: Lock wait timeout exceeded; try restarting transaction {"cluster": "test_cluster1"}
then
