I'd try profiling the problematic code. Given the magnitude of the times, sampling should be sufficient which means you could do this on production when the problem happens. You'll probably need to configure it to log JVM internal calls. I use YourKit (because they give me a free license to use to develop Tomcat). Other profilers are available.
