请发完整的crash log出来好么？这边贴不下的话可以放在Github的gist或者pastebin之类的地方。

光看开头部分这crash log所显示的版本信息跟我知道的版本都不一样。Oracle JDK6u31里的HotSpot VM应该是版本25.x的，但这里却是17.0。
这个是SAP维护的版本的HotSpot VM么？这个IA-64 port的源码我手上没有，手边也没IA-64的机器可用，所以恐怕很难帮啥忙。最好还是找SAP的技术支持去问…

抱歉，我错了。查了一下，Oracle确实是有出IA-64版JDK6的update 30几，里面的HotSpot VM都是17.0的。例如这个：http://www.oracle.com/technetwork/java/javase/downloads/javase-6u33-itanium-release-notes-1661429.html
不过我还是没啥头绪…

R大，内存不够会不会出现这个问题，我看这个err文件中Memory: 16k page, physical 8177904k(110080k free) free内存只有110M？

不像。物理内存也还有110M的话还能容纳很多小东西的分配。再说swap的剩余空间也还挺多的。

看了下出错地址是0x200000005ee00030，不在page边界上。谁有Itanium的反汇编器求一个啊
