What the other James and Dave said actually makes some sense now that I think about it. Read http://java.sun.com/javase/technologies/hotspot/index.jsp-- it explains what hotspot optimization does.
Basically, your JVM will actually change how it is compiling code after your server had been running for a while and "warmed up". It keeps track of pieces of code that run A LOT. Those are "hot spots" in your application and could use a little extra boost of performance. Therefore, the hotspot compiler will compile those parts down to "optimized machine instructions". It is costly to do that, but if that code is called enough, it could be worth it because the is much faster. What we are suggesting is that after your server has been up for a while, the HotSpot compiler finds some code it thinks it can optimize, but it crashes instead. Perhaps, if you examine the content of the error file you can get some info. Generally, it's not too awful useful though. As far as how to debug, I don't know. If you provide the proper arguments to your JVM, the hotspot compiler will be disabled. That will at least allow you to confirm if it fixes the problem. Your overall performance will probably suffer though. ~Brad ----- Original Message ----- From: "James Wolfe" <[EMAIL PROTECTED]> To: "CF-Talk" <[email protected]> Sent: Tuesday, August 26, 2008 9:47 AM Subject: Re: PID errors - much simpler > Our JVM is fully updated.
