Troubleshooting crashing MySQL instance

Hey folks, Hopefully I can ask this question with enough clarity and detail to get a meaningful answer! I'm a java developer, but trying to debug what's going on with this MySQL instance.
I have a couple environments: local, dev, perf. In only one of them, MySQL is crashing about 1/4-1/3 times during a Flyway migration. First flyway clean empties the DB, then flyway migrate is run - but only in this environment is it problematic. Some of the logs (see the very end) looked like there was something corrupt in one of the InnoDB tables - I tried just cleaning out everything and reinstalling MySQL (and did make sure to empty out /valib/mysql as well) but that didn't resolve the problem. As I said, this will happen once, then it'll run 3 or 4 times without a hitch before doing it again. This instance is on a virtual machine outside my immediate control.
Any suggestions on how to resolve this?
This is the flyway log we get: Database: jdbc:mysql://fooperfdb01:3306/foo_perf (MySQL 5.7) Successfully validated 614 migrations (execution time 00:00.559s) Creating Metadata table: `foo_perf`.`schema_version` ERROR: Unable to commit transaction java.sql.SQLNonTransientConnectionException: Connection is close at org.mariadb.jdbc.internal.util.ExceptionMapper.get(ExceptionMapper.java:123) at org.mariadb.jdbc.internal.util.ExceptionMapper.throwException(ExceptionMapper.java:69) at org.mariadb.jdbc.MariaDbStatement.executeQueryEpilog(MariaDbStatement.java:259) at org.mariadb.jdbc.MariaDbStatement.execute(MariaDbStatement.java:287) at org.mariadb.jdbc.MariaDbStatement.execute(MariaDbStatement.java:340) at org.mariadb.jdbc.MariaDbConnection.commit(MariaDbConnection.java:504) at org.flywaydb.core.internal.util.jdbc.TransactionTemplate.execute(TransactionTemplate.java:88) at org.flywaydb.core.internal.command.DbMigrate.migrate(DbMigrate.java:173) at org.flywaydb.core.Flyway$1.execute(Flyway.java:959) at org.flywaydb.core.Flyway$1.execute(Flyway.java:917) at org.flywaydb.core.Flyway.execute(Flyway.java:1361) at org.flywaydb.core.Flyway.migrate(Flyway.java:917) at org.flywaydb.commandline.Main.executeOperation(Main.java:139) at org.flywaydb.commandline.Main.main(Main.java:102) Caused by: org.mariadb.jdbc.internal.util.dao.QueryException: Connection is close at org.mariadb.jdbc.internal.protocol.AbstractQueryProtocol.checkClose(AbstractQueryProtocol.java:762) at org.mariadb.jdbc.internal.protocol.AbstractQueryProtocol.sendQuery(AbstractQueryProtocol.java:385) at org.mariadb.jdbc.internal.protocol.AbstractQueryProtocol.executeQuery(AbstractQueryProtocol.java:380) at org.mariadb.jdbc.internal.protocol.AbstractQueryProtocol.executeQuery(AbstractQueryProtocol.java:337) at org.mariadb.jdbc.MariaDbStatement.execute(MariaDbStatement.java:277) ... 10 more ERROR: Unable to restore autocommit to original value for connection java.sql.SQLNonTransientConnectionException: Connection is close at org.mariadb.jdbc.internal.util.ExceptionMapper.get(ExceptionMapper.java:123) at org.mariadb.jdbc.internal.util.ExceptionMapper.throwException(ExceptionMapper.java:69) at org.mariadb.jdbc.MariaDbStatement.executeQueryEpilog(MariaDbStatement.java:259) at org.mariadb.jdbc.MariaDbStatement.execute(MariaDbStatement.java:287) at org.mariadb.jdbc.MariaDbStatement.executeUpdate(MariaDbStatement.java:470) at org.mariadb.jdbc.MariaDbStatement.executeUpdate(MariaDbStatement.java:486) at org.mariadb.jdbc.MariaDbConnection.setAutoCommit(MariaDbConnection.java:487) at org.flywaydb.core.internal.util.jdbc.TransactionTemplate.execute(TransactionTemplate.java:96) at org.flywaydb.core.internal.command.DbMigrate.migrate(DbMigrate.java:173) at org.flywaydb.core.Flyway$1.execute(Flyway.java:959) at org.flywaydb.core.Flyway$1.execute(Flyway.java:917) at org.flywaydb.core.Flyway.execute(Flyway.java:1361) at org.flywaydb.core.Flyway.migrate(Flyway.java:917) at org.flywaydb.commandline.Main.executeOperation(Main.java:139) at org.flywaydb.commandline.Main.main(Main.java:102) Caused by: org.mariadb.jdbc.internal.util.dao.QueryException: Connection is close at org.mariadb.jdbc.internal.protocol.AbstractQueryProtocol.checkClose(AbstractQueryProtocol.java:762) at org.mariadb.jdbc.internal.protocol.AbstractQueryProtocol.sendQuery(AbstractQueryProtocol.java:385) at org.mariadb.jdbc.internal.protocol.AbstractQueryProtocol.executeQuery(AbstractQueryProtocol.java:380) at org.mariadb.jdbc.internal.protocol.AbstractQueryProtocol.executeQuery(AbstractQueryProtocol.java:337) at org.mariadb.jdbc.MariaDbStatement.execute(MariaDbStatement.java:277) ... 11 more ERROR: Error restoring current schema to its original setting And the mysqld log at the same time:
