[resolved] Cannot open connection exception

Hi
I've created a few jobs to insert/update data in MDM. I orchestrated these job. When I want to run these jobs I sometimes get the following error:
org.hibernate.exception.GenericJDBCException: Cannot open connection; nested exception is:
       com.amalto.core.util.XtentisException: org.hibernate.exception.GenericJDBCException: Cannot open connection

This error causes the whole chain to fail. I get this error in different child jobs and the jobs in which the error appears seem to be different every time I run the whole process.
How can I resolve this issue?
Kind regards
Dries

Hi,
Could you check in the server log (jboss_dir/server/default/log/server.log) for a more detailed exception? It looks like MDM server is unable to insert data in the underlying database for some reason.

Hi
Thanks for your reply and sorry for my late reply.
We resolved the issue by restarting our MDM server.
Kind regards
