If you are getting OOM-kills from the kernel, that usually means you
have system-wide memory exhaustion.

Since the size of a JVM is roughly constant, I would guess that the
problem actually lies in your C code.

Alternatively your system just doesn't have enough virtual memory
configured to do whatever it is you're trying to do. Add more swap.

Either way, it doesn't look like a JDBC driver problem based on the
information you have given.
