Issue while deploying BDM in Bonita studio

Hello,

We have around 50+ processes deployed on our local Bonitasoft 7.5.4 server. After I deploy all the processes, if I try to deploy a BDM change, the local H2 instance is throwing Out of Memory error as shown below and after this error, when I try to launch the portal a 500 error is being thrown and the only way to come out of this is to delete the local Bonita database file(bonita_journal.db.h2.db) which deletes all the deployed process. Hence, this has become a deadlock to us.

Any in-sight in to this problem is highly appreciated.

Below are prominent logs to my observation:

org.hibernate.engine.jdbc.spi.SqlExceptionHelper Out of memory.; SQL statement:
