嘗試將Apache Tomcat端口從8080更改爲80時出現內存錯誤

Question

我想讓我的VPS上的Tomcat安裝在端口80上而不是8080上運行，但是當編輯server.xml文件的設置時在我的Tomcat的目錄，並嘗試重新啓動Tomcat，我得到這個錯誤：

Jan 23, 2012 9:55:46 AM org.apache.coyote.http11.Http11Protocol init SEVERE: Error initializing endpoint java.net.SocketException: Cannot allocate memory at java.net.PlainSocketImpl.socketBind(Native Method) at java.net.AbstractPlainSocketImpl.bind(AbstractPlainSocketImpl.java:353) at java.net.ServerSocket.bind(ServerSocket.java:336) at java.net.ServerSocket.(ServerSocket.java:202) at java.net.ServerSocket.(ServerSocket.java:158) at org.apache.tomcat.util.net.DefaultServerSocketFactory.createSocket(DefaultServerSocketFactory.java:50) at org.apache.tomcat.util.net.JIoEndpoint.init(JIoEndpoint.java:538) at org.apache.coyote.http11.Http11Protocol.init(Http11Protocol.java:176) at org.apache.catalina.connector.Connector.initialize(Connector.java:1014) at org.apache.catalina.core.StandardService.initialize(StandardService.java:680) at org.apache.catalina.core.StandardServer.initialize(StandardServer.java:795) at org.apache.catalina.startup.Catalina.load(Catalina.java:524) at org.apache.catalina.startup.Catalina.load(Catalina.java:548) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:616) at org.apache.catalina.startup.Bootstrap.load(Bootstrap.java:261) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:413) Jan 23, 2012 9:55:46 AM org.apache.catalina.startup.Catalina load SEVERE: Catalina.start LifecycleException: Protocol handler initialization failed: java.net.SocketException: Cannot allocate memory at org.apache.catalina.connector.Connector.initialize(Connector.java:1016) at org.apache.catalina.core.StandardService.initialize(StandardService.java:680) at org.apache.catalina.core.StandardServer.initialize(StandardServer.java:795) at org.apache.catalina.startup.Catalina.load(Catalina.java:524) at org.apache.catalina.startup.Catalina.load(Catalina.java:548) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:616) at org.apache.catalina.startup.Bootstrap.load(Bootstrap.java:261) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:413)

不能確定這意味着什麼？這是否意味着我沒有足夠的內存？是否有其他方法讓Tomcat在80端口上運行？

編輯：這裏是輸出，當我在免費-m類型：

total  used  free  shared buffers  cached 
Mem: 1024  748  275   0   0   0 
-/+ buffers/cache: 748  275 
Swap: 0   0   0

我得到了同樣的問題在Tomcat中使用authbind通過從OpenJDK的切換到80端口上。我解決它運行的OpenVZ Sun Java。
