Hi everyone,


We got some issues when we want to save some projects in CA PPM 14.3 SP1 or in Open Workbench since two weeks.


We have to kill Open Workbench session when it happens but updates are not saved, and in CA PPM the saving function loops without updating projects. The oracle SQL transaction is running during some hours after trying to save our updates.


We restart CA PPM services every night, sometimes projects can be saved the next day and sometimes not...


We found nothing in PRLOCK table, and we got no idea why it happens and how resolve this problem.


We got this sort of errors in app.log :

Did anyone got any idea for resolving our issue ? Help will be appreciated, thank you.
