by working with large data objects in PostgreSQL. I have tried to disable autocommit, but it didn't help. Also I have tried to configure data source taskDS to be JTA datasource, because some web discussions suggested to try using of transactions to solve this, but this didn't help too. Any help will be appreciated, thanks. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/751316#751316] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
