The listener failed to start the dedicated server process.

Question

my spring-hibernate application starts without problems during the last week , but suddenly I get below the error. Is this caused by a configuration error in applicationContext.xml? there are no errors in my oracle10g log files (I get below errors every time 1-2 times)

This has little to do with Spring, Hibernate, this is a pure Oracle problem. Here is what we can read about the ORA-125000:
