First off, try using a newer version.
Second, and most unfortunately, the library and agent don't really properly
clean up after themselves. An long running application which tries to start,
stop and restart the library or agent will definitely leak memory, and probably
have other problems as well.
The best you can hope for is that the agent doesn't have a growing leak while
running. The amount of memory allocated at startup and during request
processing should be stable. If there is a leak that increased with each
request or over time, then that's something we can look into.
