I am required to start few servers locally. 我需要在本地启动一些服务器。 I keep getting the "java.lang.OutOfMemoryError: PermGen space" error every now and then. 我一直不时收到“ java.lang.OutOfMemoryError：PermGen空间”错误。 I tried to increase my JVM size by the following command. 我试图通过以下命令来增加JVM的大小。 export MAVEN_OPTS="-Xmx128m -XX:MaxPermSize=512m" export MAVEN_OPTS =“-Xmx128m -XX：MaxPermSize = 512m”

After running the above command, I see that the MAVEN_OPTS is correctly updated. 运行上述命令后，我看到MAVEN_OPTS已正确更新。 $ echo $MAVEN_OPTS -Xmx128m -XX:MaxPermSize=512m $ echo $ MAVEN_OPTS -Xmx128m -XX：MaxPermSize = 512m

However, after a few minutes from starting the servers I get an out of memory error. 但是，在启动服务器几分钟后，出现内存不足错误。

$ echo $MAVEN_OPTS -Xmx512m:wq $ echo $ MAVEN_OPTS -Xmx512m：wq

Can someone please tell me what causes the properties to change and what does the :wq come from? 有人可以告诉我是什么导致属性更改，以及：wq来自什么？

wq is the vim command for save and exit. wq是vim命令，用于保存和退出。 Looks like your jvm options got corrupted with that. 看来您的jvm选项已损坏。 Can you remove that and retry. 您可以删除该内容并重试。

Increasing -XX:MaxPermSize is the correct thing to do here. 增大-XX:MaxPermSize是正确的做法。
