I had some memory problems with a process running over the weekend and received the following exceptions in the objectdb log:

1)

Unfortunately the process failed to produce a heap dump as the server was running out of disk space at the time so feel free to just close this issue if the stack traces are of no use to you - I thought I'd post it anyway as I've not seen the "overhead limit" exception before with objectdb.

This could happen as a result of heavy memory usage.

Read about a configuration change that may help in this forum thread.
