Re: Memory Leak in OCI Calls

Have you determined that it really is a memory leak? If the program grows larger and larger until it runs out of resources, then it's a leak.
If it simply uses more RAM that you expected then it probably isn't. In particular if the memory usage stabilises over time then it isn't leaking.

If it's a leak then you need to produce a minimal complete test program that demonstrates the problem. It should then be possible to determine if it's a known bug and if there's a patch or workaround to the problem.
