Eeeek a leak

[Spark]

I think I have my first memory leak.
My chatserver climbs all the time in memory usage, 0.1% more almost everytime "top" refreshes. After a few minutes I'm at around 10% (25 MB) even when I do nothing and there is no connection and it starts at 2%. This is a memory leak, right?
Any pointers what could cause memory leaks? My code is still small so it should be easy to find. I don't use any malloc().
Is there some good beginners tutorial about where to look for leaks?
I also noticed that my server has three threads running in top as soon as I start it. But I do only spawn one at the beginning and one for every new connection. So I would expect 2 + # of connections but it's 3 + # of connections. Is this usual?

Your code is so small, I can't even see it! Perhaps if you included it, we may have something to go on.

Well, it's not _that_ small. But I just found it, sorry! I could localize the problem and found that I was just querying a mysql db in a while loop and forgot to do a mysql_free_result() between each loop.
