org.bonitasoft.engine.business.data.SBusinessDataRepositorySerializationException: Unable to serialize list of Entity
I have these exceptions in my server log, coming regularly, with different users:
org.hibernate.engine.jdbc.spi.SqlExceptionHelper error enlisting a JdbcConnectionHandle of a JdbcPooledConnection from datasource jdbc/BusinessDataDSXA in state ACCESSIBLE with usage count 1 wrapping com.mysql.jdbc.jdbc2.optional.JDBC4MysqlXAConnection@2ceb059b on com.mysql.jdbc.jdbc2.optional.JDBC4ConnectionWrapper@1fad8129
org.restlet.Component.BonitaRestletApplication Exception or error caught in server resource org.bonitasoft.engine.command.CommandExecutionException: USERNAME=<<user>> | org.bonitasoft.engine.command.SCommandExecutionException: org.bonitasoft.engine.business.data.SBusinessDataRepositorySerializationException: Unable to serialize list of Entity
org.bonitasoft.web.rest.server.api.resource.CommonResource USERNAME=<<user>> | org.bonitasoft.engine.command.SCommandExecutionException: org.bonitasoft.engine.business.data.SBusinessDataRepositorySerializationException: Unable to serialize list of Entity org.bonitasoft.engine.command.CommandExecutionException: USERNAME=<<user>> | org.bonitasoft.engine.command.SCommandExecutionException: org.bonitasoft.engine.business.data.SBusinessDataRepositorySerializationException: Unable to serialize list of Entity
However, I cannot see any other impact on the users, and noone reported anything strange.
Anyone has any idea on where it could come from ?
Thanks,

Hello again,
We tried raising the number of connections to the MySQL database by raising the maxTotal parameter in 2 of the 3 ressources of the bonita.xml configuration file, but the error still happens as often. We're trying the last resource (on bonita_journal), which seems to open many connections, but anyone has any other idea?
Thanks,
FX
