运行时错误，难道是内存小了？

[思与悟]

不能够呀，也没报内存溢出错误，我也修改过内存大小。 # A fatal error has been detected by the Java Runtime Environment: # # EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x0000000075a3772d, pid=1684, tid=1040 # # JRE version: Java(TM) SE Runtime Environment (7.0_45-b18) (build 1.7.0_45-b18) # Java VM: Java HotSpot(TM) 64-Bit Server VM (24.45-b08 mixed mode windows-amd64 compressed oops) # Problematic frame: # C [libmx.dll+0x1772d]

让tomcat停下来内存或系统过载是主要因素！我猜也是内存问题，系统是不是有自动作业(Task)过于执行频繁

[思与悟]

用JAVA写的代码，有个定时器，每隔几秒就要通过外部接口调用Matlab程序包计算二次曲线拟合系数，一直在运行，这会影响吗？
