Or least I think it's the Relational engine that crashes since it disappears in task mgr. Both Transactional and Relational services have to be restarted for operations to resume. This server is only be used for Transactional access to btrieve files. No errors get written to the pvsw.log and nothing obvious in the Event Viewer. We've followed Pervasive guidelines for ALL the configuration settings. I'm curious if anyone else has had this type of problem with the relational engine. This has happened four times before, but at that time it was an application not closing ODBC connections. Any ideas or suggestions would be appreciated. Thanks!
