2015-03-20 1:15 GMT+02:00 Eric Robinson eric.robin...@psmnv.com: Heap dumps? What we do is called a thread dump, as far as I know. We use kill -3 on Linux, which dumps the thread activity. The memory data shows up at the bottom of that. See:

// You can look for biggest objects in heap (using MAT, Leak Suspects report, Dominators Tree report). This way you can try to find what was the exact reason of OOM instead of just thinking eh, I need to give instances more memory. MAT does things good. I've already found using MAT+JVVM the

// Mostly leaner - a 32-bit JVM uses 32-bit pointers, so object references consume less heap and stack space. Whether or not the code runs faster or slower depends on what you're doing, since the tradeoff is fewer registers available in 32-bit mode, which can lead to more register spills and

Sorry for the false alarm. A little more digging showed that an old ECJ was getting used at runtime -- because it had been thwacked into the runtime classpath. [Don't ask.] It now works fine. On 8/29/2014 9:14 AM, Mark Thomas wrote: On 29/08/2014 14:56, Jess Holle wrote: I have a web
