我遇到这种问题了，急求解答

我模态分析在运行中出现这种错误：
Fatal Error; Run Terminated
Sun Oct 28, 2007   19:48:23
An error has occurred while requesting an additional
159.153 megabytes of memory from the operating system.
To correct this problem, you may need to increase the amount
of swap space on your system.  You may also need to increase
the memory usage limits that are set for your system.
For large problems you can also try decreasing the
solram allocation setting.
At least 1.49838 gigabytes of memory are needed to run this design study.
For more information, you can search for the term
"swap space" in the online help.
我搞不清楚怎么回事，我的硬件配置都达到要求了的，内存是2G的，AMD4000+的，感觉不会是配置不够。
