RE: PID errors - much simpler
James, if the JVM crashes, it will certainly create a hs_err_pid file, but how do you know that the OP's problem is related to hotspot optimization? I'm pretty sure that hs_err_pid files are only generated for Hot Spot errors specifically. Other JVM crashes don't create them.

Re: PID errors - much simpler
Our JVM is fully updated. No love. We have the new CFImage patch from Adobe. No love. I am curious what you meant about this being a classic sign of the problem. We can often go through 7,000 images without one error and then we'll get two errors within 20 images of each other and then go another 5,000 without issue. I dont know if that is a classic sign of the problem but I am interested in learning more about what you mean and how to debug it if you are correct. - James Because the OP says they get the crash once in every ~10,000 attempts which is probably the limit at which the hotspot compiler decided to compile the given class to native code.

The HotSpot compiler only kicks in if the JVM thinks it will take less time to compile to native code and run than to just compile to bytecode and run that. So, repeated operations are one place you see this a lot. After some number of repetitions, the JVM invokes the HotSpot compiler. If there's no other way to prevent this, you can simply disable HotSpot, although that will generally make a lot of things a LOT slower.

No. Usually, I have only gotten errors like that just after a botched install CF, or when I am screwing around with stuff.

Re: PID errors - much simpler
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 cf-talk@houseoffusion.com Sent: Tuesday, August 26, 2008 9:47 AM Subject: Re: PID errors - much simpler Our JVM is fully updated.
