stress test -> com.objectdb.o.InternalException: null

I am running a stress test with 2 users, each making a request to the JSON API (which uses as storage ObjectDB) each 50 milliseconds. An API call might have between 1-4 db calls, but they are relatively light, and the db has just a few MB at the moment. After a few minutes I got this exception. If I decrease the load, it doesn't happen. If I increase it, I get it very often. Any solution/fix? A sample project is very hard, if not impossible, to create, because it uses all the system. ...
