Is there any way to force quit selenium files

Question

I am getting the following error after I run selenium for a while; note I do call webdriver.quit(). Is there a way to simply tell selenium to close all open files (or solve this another way)? I recently started to see this; note that I set System.setProperty("webdriver.http.factory", "jdk-http-client"); to try to use the new (non-dprecated) jdk http client.

My exception and code:

java.io.UncheckedIOException: java.io.IOException: Too many open files

My code:

My primary method calls
try {
   localWebDriver = getWebDriver(useFastStrategy);
   localWebDriver.get("about:blank");
   localWebDriver.get(url);
   localWebDriver.quit();
} catch (EXception e) {
   quitSafely(localWebDriver);
}
...


Other support methods:

            localWebDriver.quit();
        } catch (Exception e) {
                // nothing to do
            LOGGER.info("Got error in quit() call of quitSafely", e);
        }

    }
